• # question_answer A shaft was initially subjected to bending moment and then was subjected to torsion. If the magnitude of bending moment is found to be the same as that of the torque, then the ratio of maximum bending stress to shear stress would be: A) 0.25                             B) 0.50C) 2.0                               D) 4.0

Bending stress, $\sigma =\frac{32M}{\pi {{d}^{3}}}$ Shear stress, $\tau =\frac{16T}{\pi {{d}^{3}}}$ For M = T, $=\frac{\sigma }{\tau }=2$
