Theory of Structures
Y are the bending moment, moment of inertia, radius of curvature, modulus of If M, I, R, E, F, and elasticity stress and the depth of the neutral axis at section, then

M/I = E/R = F/Y

I/M = R/E = F/Y

M/I = E/R = Y/F

M/I = R/E = F/Y

M/I = E/R = F/Y

I/M = R/E = F/Y

M/I = E/R = Y/F

M/I = R/E = F/Y
