## **Introduction**

Throughout fiction and real life, there have been numerous feats demonstrating a certain character's or objects destructive power. This pages purpose is to consolidate calculations for those feats for better convenience in determining an objects or character's Attack Potency or Durability. Please note, these calculations are typically low-ends or averages and may not be a one-size-fits-all due to outliers. I.E. freezing of an average human will most likely not apply to one that is exceedingly large or incredibly diminutive.

**Impact Feats**

**Getting Hit by a Car**

**Getting Hit by a Car**

**If not slammed into a wall**

When being hit by a car, the linear momentum of the car+person system needs to remain the same. Linear momentum is m*v

The values vary based on the vehicle and the speed of course.

For example, assuming the human is 70 kg, the car is 1500 kg and that the car's speed is 11.176 m/s:

FinalSpeed = (MassCar*InitialSpeed):(MassPerson+MassCar)

Using the values above this is 10.677707006369426751592356687898 m/s.

KE of the person is 3990.4699419854760842224836707371 Joules

**Street level**

**If slammed into a wall**

However, it should be noted that the above calculation assumes that the person is sent flying by the car. In some odd cases in fiction, the car stops and the character tanks the attack. Or in some cases, a character is slammed into a wall by a car. In these cases, the entire KE of the car scales to the character's durability.

**KE= 1/2*mass*velocity^2** (Where mass is in kilograms and velocity is in meters per second)

**Getting Hit by a Car**

**Getting Hit by a Car**

0.5*1500*11.176^2 = **9.3677232e4 Joules - Wall level**

This value assumes that this is an average-sized car weighing in at 1500 kg and travelling at 25 mph/11.176 m/s.

When travelling at **45 mph**:
0.5(1500) * 20.1168^2 = 303,514.23168 joules, or **303.5 Kilojoules** - **Wall level**
When travelling at **60 mph**:
0.5(1500) * 26.8224^2 = 539,580.85632 joules, or **539.5 Kilojoules** - **Wall level**
When travelling at **70 mph**:
0.5(1500) * 31.2928^2 = **734,429.49888 joules, or 734 Kilojoules - Wall level**

Here are some values for other vehicle types and the like.

**Getting Hit by a Bus**

**Getting Hit by a Bus**

The average "traditional-sized" school bus weighs in at 10,659.421 kg.

**25 mph (Average suburb speed)**= 0.5(10,659.421) * 11.176^2 = 665,696.702668 joules, or **666 Kilojoules** - **Wall level**

**45 mph (Daily City travel speed)**= 0.5(10,659.421) * 20.1168^2 = 2,156,857.31665 joules, or **2.15 Megajoules** - **Wall level**

**60 mph (Traditional interstate travel speed)**= 0.5(10,659.421) * 26.8224^2 = 3,834,413.00737 joules, or **4 Megajoules** - **Wall level**

**70 mph (Highway speed limit)**= 0.5(10,659.421) * 31.2928^2 = 5,219,062.14892063232 joules, or **5.22 Megajoules - Wall level**

**Getting hit by a Pickup Truck**

**Getting hit by a Pickup Truck**

The average pickup trucks can weigh over 4082.3 kg.

**25 mph (Average suburb speed)**= 0.5(4,082.3) * 11.176^2 = 254,945.709462 joules, or **255 Kilojoules** - **Wall level**

**45 mph (Daily City travel speed)**= 0.5(4,082.3) * 20.1168^2 = 826,024.098658 joules, or **826 Kilojoules** - **Wall level**

**60 mph (Traditional interstate travel speed)**= 0.5(4,082.3) * 26.8224^2 = 1,468,487.2865 joules, or **1.5 Megajoules** - **Wall level**

**70 mph (Highway speed limit)**= 0.5(4,082.3) * 31.2928^2 = 1,998,774.362185216 joules, or **2 Megajoules - Wall level**

**Getting hit by a Semi Truck**

**Getting hit by a Semi Truck**

The average semi-truck can weigh in excess of 36,287 kg.

**25 mph (Average suburb speed)**= 0.5(36,287) * 11.176^2 = 2,266,177.145056 joules, or **2.27. Megajoules** - **Wall level**

**45 mph (Daily City travel speed)**= 0.5(36,287) * 20.1168^2 = 7,342,413.94998144 joules, or **7.34 Megajoules** - **Wall level**

**60 mph (Traditional interstate travel speed)**= 0.5(36,287) * 26.8224^2 = 13,055,127.03695416 joules, or **13 Megajoules** - **Wall level+**

**70 mph (Highway speed limit)**= 0.5(36,287) * 31.2928^2 = 17,766,828.81723904 joules, or **17.77 Megajoules - Wall level+**

**Falling from Great Heights**

**Falling from Great Heights**

The energy of a falling object can be calculated by gravitational potential energy, or PE = mgh.

However, in most cases in fiction, in order to make the character's durability impressive, the height is so great that it reaches terminal velocity (more details about that).

The terminal velocity of a human being is around 53 m/s.

Assuming the person is 70 kg:

KE = 0.5*70*53^2 = 9.8315e4 Joules

**Wall level**

Approximating that border without air resistance: 53 m/s / 9.8 m/s^2 = 5.4081632653061224s drop time.

r = (1/2)*a*t^2 gives the distance covered by such a long fall.

(1/2)*9.8*5.4081632653061224^2 = 143.316326530612242302 m

Therefore, one would have to drop 143.3 m before this calculation applies.

**A Human-Shaped Hole**

**A Human-Shaped Hole**

A common gag in fiction is that someone gets slammed towards a wall so hard that a human-sized hole is left.

The average human body has a surface area of 1.9 m^2. Divide that in half and you get 0.95m^2, or 9,500 cm^2.

Assuming that the average human head's length (meaning, front to back) is 7/8ths of the average human head's height (23.9 cm). That will be used for the depth of the crater.

7/8ths of 23.9 is 20.9125.

20.9125*9500 = 1.9866875e5 cm^3.

For fragmentation (8 j/cm^3):

198,668.75 * 8 = 1.589350e6 joules, **Wall level**

For violent fragmentation (69 j/cm^3):

198,668.75 * 69 = 1.370814375e7 joules, **Wall level+**

If the wall is made out of steel:

Fragmentation:

198,668.75 * 208 = 4.1323100e7 joules, or 0.009 Tons of TNT, **Small Building level**

Violent fragmentation:

198,668.75 * 568.5 = 1.12943184e8 joules, or 0.027 Tons of TNT, **Small Building level**

__Surviving a Fall from Low-Earth Orbit__

__Surviving a Fall from Low-Earth Orbit__

So we want to calculate how much durability one would need to survive a fall from Low Earth orbit.

Low Earth orbit starts at 160km.

We will assume that a human like creature falls and that it starts at rest.

For the weight of the creature I will assume 60 kg.

**High End**

The whole energy of the fall comes from the gravitational potential energy. So we know that in total the kinetic energy on impact can not be higher than the initial gravitational potential energy.

The potential energy is given by the formula GMm/r_1 - GMm/r_2, where M is the mass of earth, m is the mass of the object falling, r_1 is the initial distance from the center of the earth and r_2 is the final distance from the center of the earth. G is the gravitational constant.

Radius of earth is 6371000 m = r_2

r_2 + 160000m = r_1

G = 6.67408*10^-11

M = 5.972*10^24 kg

m = 60 kg

So setting in we get:

(6.67408*(10^-11) * 5.972*(10^24) * 60)/6371000 - (6.67408*(10^-11) * 5.972*(10^24) * 60) / (6371000 + 160000) = 9.1959e7 J

**Small Building level**

**Low End**

The terminal velocity for a human is 53 m/s, near the ground.

So while someone falling from great heights might initially have a higher speed when going towards the ground the speed will drop towards that value.

0.5*60*53^2 = 8.427e4 J

So at terminal velocity this would only be low end **W'***all level'*.

**What is Realistic?**

The actual value would likely lie somewhere inbetween those two.

One could try to do a more accurate method using the drag equation and the barometric formula, even though I am not quite sure whether that would work (at some point of the fall we would likely talk about supersonic stuff which it usually is hard to get the needed values for).

For now we would stay with **Wall level** for such a feat.

Also let us mention that this is only for low earth orbit falling. For higher alitudes the potential energy value would go closer to the kinetic energy when falling with escape velocity, while for lower it would mostly just stay the same (the realistic value would go towards to terminal velocity value) except for short falls where not even that much speed if attained.

**Bone Breaking Feats**

**Breaking all the Bones of a Man's Body**

**Breaking all the Bones of a Man's Body**

On average, the weight of a man's bones is 15% of their body mass, which inof itself is 88.768027 Kilograms. 15% of that is 13.31520405 Kilograms.

The density of bone is 3.88 g/cm^3, which would mean that the total volume would be 13.31520405 divided by 0.00388, which equals 3431.75362113402 cm^3 for our volume.

To get the fragmentation values, we need to use the compressive strength of bones. To quote Wikipedia, "bone has a high compressive strength of about 170 MPa (1800 kgf/cm²), poor tensile strength of 104–121 MPa, and a very low shear stress strength (51.6 MPa)"

So, low end is 51.6, mid is 104, high is 170. Plugging those all into our volume gets us....

Low End: 1.77078.486850515432e5 Joules, **Wall level**

Mid End: 3.56902376598e5 Joules, **Wall level**

High End: 5.83398115592783e5 Joules, **Wall level**

**Breaking a Human neck**

**Breaking a Human neck**

**Volume of Vertebrae**

The vertebrae that make up the neck are the cervical vertebrae and are 7 vertebrae in total. However, due to finding info only for vertebrae 3 through 7, the smallest one will be calced.

C3 pedicle: The pedicle is roughly a rectangular prism and there are two of them. 5.27 mm x 5.14 mm x 7.08 mm = 0.527 cm * 0.514 cm * 0.708 cm = 0.191781624 cm^3. 0.191781624 cm^3 * 2 = 0.383563248 cm^3

C3 vertebral body: The vertebral body is a cylinder. The mean height is 15.1 mm and the radius 7.34 mm = 2.55575 cc.

**Energy to Fragment Vertebrae**

The shear strength of bones is 51.6 MPa or J/cc

(0.383563248 + 2.55575) x 51.6 = 151.6685635968 J

**Athlete level**

Keep in mind, this is just fragmenting most of the vertebrae. This does not take into account the the lamina.

**Breaking a Bone**

**Breaking a Bone**

The durability of a bone depends on the angle of attack.

A bone of a deceased 52-year old woman only required 375 Joules of energy when the force was applied within five degrees of the orientation of the collagen fibres. But the force increased exponentially when they applied it at anything over 50 degrees away from that orientation, up to 9920 Joules when they applied a nearly perpendicular force.

So breaking a bone would require 375-9920 Joules, depending on the angle of attack. That's **Street level** to **Street level+**.

**Vaporization Feats**

__Vaporizing a Human__

__Vaporizing a Human__

**Conditions**

https://www.thoughtco.com/chemical-composition-of-the-human-body-603995

Okay, First off. To vaporize a human thoroughly at once, let’s assume the temperature change is 1800°F or 982.2°C https://www.cremationresource.org/cremation/how-is-a-body-cremated.html

Average body temperature is 97.7°F or 37.5°C

https://en.wikipedia.org/wiki/Human_body_temperature

So the temperature change is by 944.72°C

http://endmemo.com/physics/specificheat.php

https://en.wikipedia.org/wiki/Human_body_weight

The average human is 62 kilograms

**STEP I**

We will start with water

https://en.wikipedia.org/wiki/Body_water

60% of human mass is water, or 37.2 kilograms.

http://www.engineeringtoolbox.com/water-thermal-properties-d_162.html

The heat capacity of water is 4.1813 kilojoules per kilogram

Plugging the values into this calculator

Specific Heat energy is **146,945,868 joules**

Plugging in the mass of water gives us **84,247,026 joules**

Adding these two values together we get **231,189,783 J**

**STEP II**

https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/

Average amount for body fat is 2.348 kilojoules per kilogram

Fat seems to be 17% of body mass, or 10.54 kilograms going by the numbers shown

Plugging it into the specific heat energy calculator, we get **23,379,855 joules**

**STEP III**

Protein makes up 16% of body mass, which means it makes up 9.92 kilograms of the body

https://www.itis.ethz.ch/virtual-population/tissue-properties/database/heat-capacity/

Muscle has a heat capacity of 3.421 kilojoules per kilogram

Plugging it into the specific heat energy calculator, we get **32,060,320 J**.

**STEP IV**

For minerals, it makes up 6% of body mass, or 3.72 kilograms.

We will bone for this, specifically cortical bone, which is 1.313 kilojoules per kilogram.

We get **4,614,353 J**

**STEP V**

Carbohydrates make up merely 1% of human weight, or 0.62 kilograms

Heat energy of sugar (carbohydrate) is 1.255 kilojoules per kilogram.

We get **735,087 joules**

**Conclusion**

Adding them together, we get **291,982,509 J**

**Small Building level**

As noted, we took values that were simplest and closest analogs, plus we did not include the latent heat from anything other than water.

**Melting/Heat Feats**

**Surviving the Heat of the Sun**

**Surviving the Heat of the Sun**

**Surface** __1. Radiation:__ For radiation we need to know the emissivity, surface area and temperature.

The temperature of the sun is about 5500°C per Wikipedia.

For the surface area we take the surface of the average human body, since we assume that the person is submerged in the sun. The average body surface area is about 1.73 m^2 per this article.

The emissivity is about 1.2 at this temperature per this article.

Now we input this values into this calculator and get 130756044.60407 J/s.

__2. Conduction:__ For conduction we need to know surface area, thickness of the material that the heat is transmitted through, the thermal conductivity of the material and the heat of the sun and the object.

Surface area and temperature of the sun can be taken from the radiation part.

Now for the material were the heat is transmitted through we will take human skin.

Human Skin is around 3mm thick. (https://en.wikipedia.org/wiki/Human_skin)

It has a thermal conductivity of about 0.209. (http://users.ece.utexas.edu/~valvano/research/Thermal.pdf)

Normal skin temperature is about 33°C. (http://hypertextbook.com/facts/2001/AbantyFarzana.shtml)

With that we have everything we need. We use this calculator to get a result.

The result is: 658901.0633333334 watts = 658901.0633333334 J/s.

Now we add both results together to get a final value: 658901.0633333334 J/s + 130756044.60407 J/s = 1.3141494566740333*10^8 J/s. **Core** Now a similar procedure for the core. The core of the sun is about 15.7 million Kelvin hot. The emissivity of the sun at temperatures such as this isn´t known, but the article that is linked to emissivity states says that the minimum lies at 6900°C. So we will use the minimum emissivity of 0.92 for this. Now we just need to input all values in the calculators again.

__1. Radiation:__ 5.4829665830548E+21 J/s

__2. Conductiont:__ 1892212356.0633333 J/s

5.4829665830548E+21 J/s + 1892212356.0633333 J/s = 5.4829665830566922E+21 J/s

Note: This is for a human in the sun. If the character is a lot bigger or smaller than an average human, or if the character is made from another material, like for example metal, this numbers change.

**Maximum internal energy intake** If an object is heated it usually doesn´t get hotter than the source of the heat. If the object is as hot as the heat source the energy itself emits to its surroundings should be equal to the energy it is infused with.

That means there is a maximum amount of thermal energy an object can take in through a certain source of heat.

In order to calculate this energy we will just measure how much energy will be necessary to heat the object to this temperature, from the point that it has no internal energy, which should be 0K.

The specific heat capacity of a human body is 3470 J/kg.oC

Average weight of a grown human is around 62 kg.

**Surface: **The surface of the sun has a temperature of 5.773.2K.

3470*62*5773.2 = 1.242046248E+9J

That is __Building Level__.

**Core: **The core of the sun has an temperature of 15 700 000K.

3470*62*15 700 000 = 3.377698E+12J

That is __Multi-City Block Level+__.

**Melting a Plane**

**Melting a Plane**

**Specific Heat Capacity** Titanium Ti-6Al-4V = 526.3 J/kg-°C

Steel = 510 J/kg-°C

Aluminium 2024-T3 = 875 J/kg-°C

**Melting Point** Titanium = 1604 °C

Steel = 1425 °C

Aluminium = 502 °C

**Latent Heat of Fusion** Titanium = 419000 J/Kg

Steel = 272000 J/Kg (This is for Iron, but is * nearly* the same

*though*)

Aluminium = 398000 J/Kg

Total Energy = (((526.3)*(7320.98084)*(1604-25)) + ((7320.98084)*(419000))) + (((510)*(23793.1877)*(1604-25)) + ((23793.1877)*(272000))) + (((875)*(148249.862)*(1604-25)) + ((148249.862)*(398000))) = 2.9861275268025227e11 Joules, or 71.37 Tons, **City Block level+**

**Melting a Tank**

**Melting a Tank**

The mass of a tank is around 60 tons.

Materials of tanks and especially how much of which is there is mostly classified information. Using this article on composite armour we get 10% ceramics and 90% steel, given that the mechanics and everything will be made out of metal. For the ceramics we will assume Alumina, since that is also mentioned as a material used here.

Specific heat of materials: Per this article:

“c” of alumina = 850 J/(kg*K)

“c” of steel = 481 J/(kg*K)

2.2 Latent heat of fusion:

Steel: 260000 J/kg per this article.

Alumina: 620000 J/kg as per this article.

Melting point:

Alumina: 2072 °C (per wikipedia)

Steel: 1425 °C (per this)

Mass of materials: 6000 kg alumina, 54000 kg Steel

Assuming a tank is on average 20°C warm.

High end:

850 J/(kg*K)*6000 kg *(2072 °C - 20 °C) + 620000 J/kg * 6000 kg + 481 J/(kg * K) * 54000 kg * (2072 °C - 20 °C) + 260000 J/kg * 56000 kg = 8.2043848e10 Joules, **City Block level**

Low end: 850 J/(kg*K)*6000 kg *(1425 °C - 20 °C) + 620000 J/kg * 6000 kg + 481 J/(kg * K) * 54000 kg * (1425 °C - 20 °C) + 260000 J/kg * 56000 kg = 6.193897e10 Joules, **City Block level**

**Durability to Tank Lava**

**Durability to Tank Lava**

Lava can be between 700°C and 1250°C. Given that we likely don´t know the heat of the lava let's work with 700°C.

Emissivity of Lava is between 0.55 and 0.85. At the given temprature it should be around 0.65.

The average human body surface area is 1.73 m^2.

At last we input all this stats in this calculator. That results in 57182.306177806 J/s.

Now part 2 heat transfer through conduction.

Human Skin is around 3 mm thick. (https://en.wikipedia.org/wiki/Human_skin)

It has a thermal conductivity of about 0.209 (http://users.ece.utexas.edu/~valvano/research/Thermal.pdf)

Normal skin temperature is about 33°C (http://hypertextbook.com/facts/2001/AbantyFarzana.shtml)

Now we use this calculator. That gives us 80389.06333333334 J/s.

Now we add that together and get: 1.3757136951113934e5 J/s, **Wall level**

**Weather Feats**

**Destructive Energy of Winds**

**Destructive Energy of Winds**

Air is 1.225 kg/m^3 at sea level.I am going to find the energy of different winds at diffirent speeds and different sizes.

1 m^3 of air:

1 m/s = 0.6125 J = **Below Average level**

5 m/s = 15.3125 J = **Below Average level**

10 m/s = 61.25 J = **Human level **(A little over Low-End wind speed of a thunderstorm)

20 m/s = 245 J = **Athlete level+** (A little over the High-End wind speed of a thunderstorm and Low-end speed of an f0 tornado )

40 m/s = 980 J = **Street level** (Speeds of an F1 tornado and Category 1 hurricane )

50 m/s = 1531.25 J = **Street level** (An F2 tornado and Cat. 3 hurricane)

70 m/s = 3001.25 J = **Street level** (An F3 tornado and Cat. 5 hurricane)

90 m/s = 4961.25 J =** Street level** (An F4 Tornado)

115 m/s = 8100.31 J = **Street level** (An F5 tornado)

135 m/s = 11162.8 J = **Street level+** (Highest wind speed recorded on Earth)

170 m/s = 17701.3 J = **Wall level** (Great Red Spot wind speeds)

500 m/s = 153125 J = **Wall level** (Wind speed of Saturn)

600 m/s = 220500 J = **Wall level** (Wind speed of Neptune)

2415 m/s = 3572240 J = **Wall level** (Fastest wind speed ever found on a planet)

This is only for 1 cubic meter of air and not taking account higher masses of air. And in terms of wind, unless it is a gust, these wind speeds are continous and would keep on delivering the same amount of joules over and over to whatever object.

**Creating a Storm**

**Creating a Storm**

Storms are calculated with either CAPE, condensation, or KE (if applicable). You can read more about that here. Usually the storm clouds extend all the way to the horizon. The visibility on a normal day is 2000 km.

Storm clouds have a height of 8000 m.

π×8,000×20,000^2 = 10053096491487 m^3.

Multiplying that by 1.003 (density of cloud) gives us 10083255780961 kg.

**Condensation** So, a storm is generally 1-3 grams per meter. We'll use 1 gram for this, so, it's 10053096491487 g, 10053096491.487 kg.

Now, for condensation, the value is 2264705 j/kg, so, put that with the above and it's

2.2767297889753066335e16 Joules, 5.44151479200599 Megatons, **Small City level+**

**KE**

KE is a bit reliant on a specific timeframe, however in this case, the standard assumption is a minute. However, if it takes less then a minute, then you can make your own calc, assuming the storm qualifies for KE Standards

20000/60 is 333.333333333333 m/s

**Earth Feats**

**Destroying the Surface of the Earth**

**Destroying the Surface of the Earth**

Earth's circumference = 40075 km

Explosion radius = **20037.50 km**

Y = ((x/0.28)^3)

Y is in kilotons, x is radius in kilometers.

Y = ((20037.50/0.28)^3) = 366485260009765.63 Kilotons of TNT

Only 50% of the total energy of the explosion is actually from the blast, so we need to halve the result. This part can be ignored if the explosion was an actual nuclear explosion.

366485260009765.63/2 = 183242630004882.82 Kilotons of TNTm, or 183.24 Petatons of TNT, **Multi-Continent level**

**Shaking the Earth**

**Shaking the Earth**

This method assumes that all they're doing is causing the Earth to quake via sheer brute Force. This is what is usually used for the standard Earthquake feat, but, if there's sufficient evidence they're also moving the plates via magic or sheer rule of cool, you can move to the next section.

Either way, first we'll need to determine the kind of magnitude needed to cause the entire Earth to quake. We'll assume that it feels like a Magnitude 4 across the world, just standard noticable shaking with no real damage.

To find how strong of an impact it truly was, you use this equation:

(Magnitude at distance) + 6.399 + 1.66×log((r/110)×((2×π)/360)) = Richter Magnitude of Earthquake, with r representing the distance away from it.

In our case, it would be, using half of the Circumference of earth,

(4)+6.399+1.66×log((20037.5÷110)×((2×π)÷360)) = Magnitude 11.2328648415393

Now, we take the magnitude and use the formula for a joulecount from said magnitude listed in Earthquake Calculations

10^(1.5*(11.2328648415393)+4.8) is 4.459613919339E21 Joules, 1.06587330768147 Teratons, **Small Country level**

**The Earth's Rotational Energy**

**The Earth's Rotational Energy**

(Picture) The formula of the rotational energy is K= 1/2* Ι*ω^2

The moment of inertia of a sphere is 2/5mR^2

The Earth's angular velocity is 7.3*10^-5 rad/s

Earth's Mass = 5.97e24 kg

Earth's radius = 6372000 m

Κ = 1/2*Ι*ω^2 = 1/5 * m*R^2 *ω^2 = 2.58e29 Joules, **Moon level**

**Freezing Feats**

**Freezing a Human**

**Freezing a Human**

Average human weight = 62kg

On average 65% of the human body weight is water.

So water mass = 0.65*62kg.

So total energy = 62 * 3500 * 38 + 0.65*62*1000*333.55 =21,688,065 Joules, **Small Building level**

**Crushing Feats**

**Crushing a Golf Ball**

**Crushing a Golf Ball**

**Materials of Golf Ball**

**Energy Density of Materials**

I will use compressive strength rather than shear since this is crushing the ball.

Polybutadiene = 2.35 MPa on average or 2.35 J/cc

Polyurethane = 7305.75 PSI = 50.37137309 MPa = 50.37137309 J/cc on average

**Volume of Ball**

The core of the ball is 3.75 cm in diameter. The ball itself can be no less than 4.267 cm in diameter.

The core would be 27.61 cc. The entire ball would be 40.68 cc. To find the volume of the cover, subtract the core volume from the entire volume to get 13.07 cc for the cover.

**Energy to Crush Golf Ball**

2.35*27.61 = 64.8835 joules for core

13.07*50.37137309 = 658.3538463 joules for cover

**Crushing a Human Skull**

**Crushing a Human Skull**

Compressive Strength of Bone - 170 MPa

Weight of the Skull - 997 g

Density of Bone - 1.6 g/cm^3

997/1.6 = 623.125 cm^3

170 MPa*623.125 cm^3 = 105,931 J

For shear strength:

Shear Strength of Bone - 51.6 MPa

56.1 MPa*623.125 cm^3 = 34,960 J

**Results**

Head Crush (Compressive) - 1.05931e5 Joules, **Wall level**

Head Crush (Shear) - 3.496e4 Joules, **Wall level**

**NOTE:** In case the skull is destroyed in a swift blow, the shear value would apply, and in the case of the head being slowly crushed to pieces, the compressive value would apply.

**Mass and Weight of Materials**

The EPA stated that an average vehicle produced in 2016 weighed, on average, 4,035 lbs. or **1830.245 kg**

On average, 900 kg of steel is used in the making of a vehicle. or **49.1737444 %** of the car.

as of 2015, The average vehicle uses 397 lbs of aluminum. or **180.076 kg** at **9.838901349272913 %** of the car.

The highest amount of copper used in an average conventional car is 49 lbs. or **22.226 kg**at **1.2143729391420275 %** of the car.

The amount of glass in an average vehicle is 100 lbs. or **45.3592 kg** at **2.478313012738732%** of the car

Plastic makes up 10% of the weight of a car. or **183.0245 kg**

Tires are made up of 14% natural rubber and 27% synthetic rubber with an average weight of 25 lbs. or **11.3398 kg**. 14% of the tires is **1.5875720000000002 kg**. 27% is **3.0617460000000003** kg. Since there are 4 tirse we will time these numbers by 4. The total weight lf natural rubber is **6.350288 kg**, or **0.3469638217834225 %** of the car. The total weight of synthetic rubber is **12.246984 kg**, or **0.6691445134394576%** of the car.

The amount of cast iron in an average car is about 7.2%. or **131.77764000000002 kg**.

This all accounts for about 80.92144004% of the weight for the car.This isn't at 100% but this is as much percentage of materials that could be found, so consider this a low-ball or a near complete fragmentation of a car.

**Destroying a Tree**

**Destroying a Tree**

**Volume of Tree**

A white oak tree will be used since they are somewhat common and are not overly large.

White Oak = 30 m height, 1.27 meter diameter

Plugging this into the formula for volume of a cylinder since tree trunks are cylindrical = 38 m^3

**Energy to Destroy Tree**

**Breaking off a Lock**

**Breaking off a Lock**

**Volume of shackle**
This is a fairly standard lock.

There will be no measurement to how much energy it takes to completely fragment a lock since most are just broken off. So, it will be just the measurement of the shackle and not the rest of the lock.

The lock is one inch or 61 px. or 0.04163934426 cm a pixel

Red = Portion that is a cylinder is 44 px or 1.832131147 cm

Pluging in the values of the radius of the shackle with the height gives me 1.78 cc x 2 = 3.56 cc for both sides. But, this doesn't take into account the curved portion. So to find the volume of that, I'll just use the volume of a torus x 0.5.

Orange = Major radius 30 px or 1.249180328 cm

This gives a volume of 2.36 cc

2.36 + 3.56 = 5.92 cc

Since this is just breaking off the lock, the shackle is not usually fragmented completely, so it would be best to just use 1/4 of the volume = 1.48 cc

**Energy to Destroy Shackles**

To find shear strength from tensile strength, just times the ultimate tensile strength by 0.60.

Fragmentation: 25740.74*8.34 = 2.146777716e5 Joules, **Wall level**

Violent fragmentation: 25740.74*18.34 = 4.720851716e5 Joules, **Wall level**

Pulverization: 25740.74*46.935 = 1.2081416319e6 Joules, **Wall level**

**Shattering a Windshield**

**Shattering a Windshield**

**Normal glass**

Danny Hamilton measured the windshield's dimensions to be 46 inches for the top length, 35 inches for height and 56.5 inches for bottom length. That's 116.84 cm, 88.9 cm and 143.51 cm.

Area of a trapezium is (a+b)/2*h

(116.84+143.51)/2*88.9 = 11 572.5575 cm^2

https://en.wikipedia.org/wiki/Laminated_glass#Specifications

A typical laminated makeup is 2.5 mm glass, 0.38 mm interlayer, and 2.5 mm glass. This gives a final product that would be referred to as 5.38 laminated glass.

For the glass:

11572.5575*0.5 = 5786.27875 cm^3

For the plastic layer:

11572.5575*0.038 = 439.757185 cm^3

Fragmentation of glass is 0.75 j/cc.

According to this the plastic is PVB. It's tensile strength is 19.6 MPa. Shear strength is 0.577 of tensile strength. 11.3092 MPa, or 11.3092 j/cc.

Fragmentation of the glass: 5786.27875*0.75 = 4339.7090625 Joules

Fragmentation of the plastic: 439.757185*11.3092 = 4973.301956602 Joules

In total that's 9313.011019102 Joules, **Street level+**

**Blowing up Cannons**

**Blowing up Cannons**

This is about blowing up 16th century cannons.

Density of cast iron is = 7.8 g/cm^3

9100000 g / 7.8 g/cm^3 = 1166666.667 cm^3 of iron

20 j/cc for iron frag, so we get...

23333333.34 Joules, 0.0055768005114723 tons of TNT, **Small Building level**

**Miscellaneous Feats**

**Digging up from the Underground**

**Digging up from the Underground**

Sometimes characters (usually monsters) burst out from underground.

Assuming the character's height is the height, and that the character's shoulder width is the width:

Height: 175 cm.

Width: 61 cm, 30.5 for the radius.

So the volume is 5.11e5 cubic centimeters.

Fragmentation:

5.11e5*8 = 4.088e6 Joules, **Wall level**

Violent fragmentation:

5.11e5*69 = 3.5259e7 Joules, or 0.008 Tons of TNT, **Small Building level**

If the ground is made out of steel:

Fragmentation:

5.11e5*208 = 1.06288e8 Joules, or 0.025 Tons of TNT, **Small Building level**

Violent fragmentation:

5.11e5*568.5 = 2.905035e8 Joules, or 0.069 Tons of TNT, **Small Building level**

- Please be noted that this is only for a quick bursting out, not slow digging.

**Throwing a Person to the Horizon**

**Throwing a Person to the Horizon**

Another common gag in fiction is that a person is punched/thrown so hard they reach the horizon/they fly out of sight.

On a normal day the visibility is usually 20 km.

Since an angle of 45 degrees requires the least force, that will be used as a low-ball.

Range of trajectory formula for 45 degrees angle is R = V^2/g. So now we can extract initial velocity from it: V = sqrt(R*g).

V = sqrt(20000*9.81) = 442.95 m/s

KE = 70*442.95^2*0.5 = 6.8671645875e6 Joules, **Wall level**

**Throwing a Person above the Clouds**

**Throwing a Person above the Clouds**

Cloud height is usually 2000 m.

Formula is (close to earth): initial speed = sqrt(2*9.81*peak height). So in this case sqrt(2*9.81*2000) = 198 m/s

Using 70 kg for the human weight: 0.5*70* 198^2 = 1.37214e6 Joules, **Wall level**

**Punching a Hole through Doors**

**Punching a Hole through Doors**

The average surface area of a human fist is 25 cm^2. The average thickness of a door is 3.334 cm thick. 83.35 cm^3. Values taken from here. For pulverization I'll use the average value.

**Wood Door**

Fragmentation: 83.35*8.34 = 695.139 Joules, **Street level**

Violent fragmentation: 83.35*18.34 = 1528.639 Joules, **Street level**

Pulverization: 83.35*46.935 = 3912.03225 Joules, **Street level**

**Steel Door**

Fragmentation: 83.35*208 = 1.73368e4 Joules, **Wall level**

Violent fragmentation: 83.35*568.5 = 4.7384475e4 Joules, **Wall level**

Pulverization: 83.35*655 = 5.459425e4 Joules, **Wall level**

**Punching through a Wall**

**Punching through a Wall**

Walls are 3/4 inch thick. That's 1.905 cm.

The human fist is 25 cm^2.

25 cm^2*1.905 = 47.625 cm^3

**Wood Wall**

Fragmentation: 47.625*8.34 = 397.1925 Joules, **Street level**

Violent fragmentation: 47.625*18.34 = 873.4425 Joules, **Street level**

Pulverization: 47.625*46.935 = 2235.279375 Joules, **Street level**

**Steel Wall**

Fragmentation: 47.625*208 = 9906 Joules, **Street level+**

Violent fragmentation: 47.625*568.5 = 2.70748125e4 Joules, **Wall level**

Pulverization: 47.625*655 = 3.1194375e4 Joules, **Wall level**
