Question : 119 of 200

Marks: +1, -0

If a circular shaft is subjected to a torque T and bending moment M, the ratio of maximum bending stress and maximum shear stress is given by

Solution:

Maximum bending stress

(σ_b) = {32M}/{πd^33}

Maximum shear stress Tmax

= {16T}/ {πd^3}

Ratio of maximum bending stress and maximum shear stress

= {2M}/T
