ϕ=TLGJphi equals the fraction with numerator cap T cap L and denominator cap G cap J end-fraction (Note: is the polar moment of inertia; for solid shafts). 3. Pure Bending

σ=PAsigma equals the fraction with numerator cap P and denominator cap A end-fraction The deformation per unit length. Mechanics of Materials - Formulas and Problems:...

Bending moments cause internal stresses that vary linearly from the neutral axis. ϕ=TLGJphi equals the fraction with numerator cap T
