Yang is 1.73 m
1.73 / 413 = .00418886198 m/px
.00418886198 / 413 = 1.73 m / 2 = .865 m
1.73 / 249 = .00694779116 m/px
.00694779116 x 682 = 4.7383935743 m
Area of a cylider = 30.45 m^2
Shear strength of concrete is 17 MPa or 2465.64 psi
Force = 30.45 m2 * 1.7e+7 Pa = 517650000 Newtons, 52785609.764802 kg (Class M)
Ugarik Adjustment:
The force was applied horizontally, so the cross sectional area should be pi*r^2, or 2.35061816323 m^2
Force = 2.35061816323 m2 * 1.7e+7 Pa = 39960508.7749 Newtons, 4074837.867669508 kg (Class M)
Yang brought this punch to a dead stop with her semblance active, and Yatsuhashi, Velvet, and the Arma Gigas stopped it through sheer strength
