Introduction[]
I'll be calculating All Might's lifting strength.
Calculation[]
Scan 1
All Might Height = 2.2 m (179 px)
Steel Bar Height = 6.19441340782 m (504 px)
Scan 2
Steel Bar Height = 6.19441340782 m (26 px)
Steel Bar Length = 341.169230769 m (1432 px)
Scan 3
Steel Bar Height = 6.19441340782 m (148 px)
Steel Bar Width = 4.98064321304 m (119 px)
Volume = 6.19441340782x341.169230769x4.98064321304 = 10525.8087518 m^3
Steel Density = 8050 kg/m^3
Steel Bar Weight = 10525.8087518 x 8050 = 84732760.452 kg
Frame 1 and Frame 2
Now to find the speed of this Steel Bar.
Steel Bar Height = 6.19441340782 m (108 px)
Distance Steel Bar Moved = 53.6849162011 m (936 px)
This is the distance the Bar moved in only 1 frame, the movie runs at 25 fps.
Timeframe = 1/25 = 0.04 seconds
Speed = 53.6849162011/0.04 = 1342.12290503 m/s
Kinetic Energy = 0.5x84732760.452x1342.12290503^2 = 7.6314302e+13 Joules
Now we can find force this Steel Bar had.
Acceleration = Distance*2/Time^2
Acceleration = 53.6849162011*2/0.04^2 = 67106.1453 m^2
Force = Mass x Acceleration
Force = 84732760.452*67106.1453 = 5.6860889e+12 Newtons, 579819703977 kg, 579819703 Metric Tons (Class G)
All Might was unmoved by five of these and continues to hold them back, so his actual lifting strength should be multiplied by five.
All Might's Lifting Strength = 579819703977 x 5 = 2899098519885 kg or 2899098519 Metric Tons (Class T)
