If a circular shaft is subjected to a torque 'T' and a Bending Moment M. The ratio of maximum shear stress to the maximum bending stress is
- A. 2M/T
- B. T/2M
- C. 2T/M
- D. M/2T
Answer: B. T/2M
Explanation: Max shear stress \tau = 16T / \pi d³. Max bending stress \sigma = 32M / \pi d³. Ratio \tau / \sigma = (16T) / (32M) = T/2M.
