## Introduction

In FMA, Kimblee causes a massive explosion during his fight with Edward.

I'll be finding the strength of this explosion to find Edwards durability.

## Calculation

• Scan 1

Scan 1

Window Height = 1.5 m (7 px)

Explosion Diameter = 90.8571428571 m (424 px)

W = R^3*((27136*P+8649)^(1/2)/13568-93/13568)^2

W is yield in tons of tnt, R is radius in meters, and P is pressure of the shockwave in bars, the standard overpressure is 20 psi or 1.37895 bars.

45.4285714286^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 7.53481780154 Tons of TNT (Large Building level+)

Scan 2

Kimblee Height = 175 cm / 7.5

Head Size = 23.3333333 cm (46 px)

Edward Height = 149 cm / 7.5

Head Size = 19.8666667 cm (79 px)

Screen Height = 473 px

Angular Size = object size*panel height in pixels/[object height in pixels*2*tan(70deg/2)]

23.3333333*473/[46*2*tan(70deg/2)] = 171.326016071 cm

19.8666667*473/[79*2*tan(70deg/2)] = 84.9380483038 cm

Distance = 171.326016071 - 84.9380483038 = 86.3879677672 cm or 0.863879677672 m

Using the ideal weight calculator to find Edward's weight (52.0 kg), and this to find his surface area. (1.45 m^2)

Now using the inverse-square method I'll find out how much energy Edward actually took.

(7.53481780154) / (4π/2((0.863879677672)^2)) = 1.60689082733 Tons of TNT m^2. Now we multiply half of Edward's surface area with that, and we get 1.16499584981 Tons of TNT (Building level+)
