Introduction[]
In this blog, I will be reviewing various feats of grappler baki in terms of lifting strength
Baki's clutching a rock[]
Baki's height and weight at that time = 167 cm = 71 kg
Using this body area calculator we get 1.7973 m^2
Palm area = 0.83% of body area = 0.0149 m^2.
Compressive strength of the stone = 100 MPa
We multiply by two, since the feat was accomplished with one hand.
100*10^6*0,0149*2 = 303,8 tons (Class K)
Jack bends the barbell's shaft[]
Head of an old man with the height of an average person(172 cm) = 81 pixels = 24.6 cm
Boom length = 831 pixels = 252.37 cm
Diameter = 16 pixels = 4.859 cm
Radius = 2.4295 cm
Shape = cylinder
S = 2πR(h+R)
S = 2 × π × 2.4295 × (252.37 + 2.4295) = 3889.5 cm^2
Yield strength of steel = 350 MPa
(3889,5/10 000)*350 000 000 = 13882.5 tons (Class M)
Oliva is compared to a giant tree[]
Olive's height = 180 cm = 847 pixels.
Judoist height = 1090 pixels = 231.6 cm
Head = 29 cm
Moving on
Head = 142 pixels = 29 cm
Tree Diameter = 1477 pixels = 301.64 cm
Radius = 150.82 cm
The tree looks a lot like a sequoia, given its diameter and structure.
The height of a sequoia according to wikipedia can easily reach 90 meters.
Tree shape = cylindrical
V = π*1,5082^2*90 = 643,147 m^3
As for density.I couldn't find much data on the density of sequoia,so I'll just find it.
Tree volume = 1487 m^3
Weight of tree = 6,167,000 kg
Density = 4147 kg/m^3
643,147*4147 = 2667,13 tons (Class M).
It turns out that the Olive is pressing down on the ground with an insane amount of strength.
Oliva compression strength[]
Olive's height = 1160 pixels = 180 centimeters
Door Height = 1160 pixels = 180 centimeters
Moving on
Door Height = 1160 pixels (that's a crazy coincidence) = 180 centimeters
Door Width = 654 pixels = 101.48 centimeters.
101.48*180 = 18266.4 cm^2.
Compressive strength = 250 MPa
(18266.4/10 000)*250 000 000 = 46569,4 tons (Class M)
Pickle throws a dinosaur[]
Pickle = 245 cm = 255 pixels
Width = 472 pixels = 453.49 cm
Moving on
Common Triceratops = 6.85 meters = 736 pixels
Width = 91 pixels = 0.84 meters
Average weight of a triceratops according to wikipedia = 9.1 tons.
(4.5349/0.84)^3*9.1 = 1431.8 tons (Class M)
Yujiro sagged the sturdy glass under his body[]
For the material we will use bulletproof glass, because the conditions of the pikl would not allow to keep it in a chamber with ordinary glass (The glass itself is also very thick, and instead of just crumbling it bent under the body).
Yujiro's height and weight = 190 cm = 120 kg.
Body area = 2.4667 m^2
Face area is about 3.7% of body area = 0.0912679 m^2
Flexural strength of bulletproof glass = 742 MPa
742*10^6*0,0912679 = 6906 tons (Class M)
Young Yujiro breaks down a Kalashnikov rifle[]
Kalashnikov barrel = 410 mm = 41 cm = 559 pixels
Bent part = 215 pixels = 15.76 cm
Thickness of bent part = 33 pixels = 2.42 cm
Radius = 1.21 cm
The shape of the muzzle is most similar to a cylinder, so that's what we'll use.
V = 2*π*1.21*(15.76+1.21) = 129 cm^2
Barrels are usually made of 50PA steel, whose yield strength = 375 MPa.
375 000 000*(129/10000) = 493,3 tons (Class K).
Conclusion[]
We have a total of 2 K-class and 5 M-class calculations, so that characters who are sufficiently strong in physical strength (Oliva, Pickle, Baki, Yujiro, Musashi, Hanayama, Sukune and the like) should be promoted to M-class, while the rest of the verse gets K-class thanks to two calculations that took place at the time of the first parts of the manga.
