Question

A long shaft of diameter d is subjected to twisting moment T at its ends. The maximum normal stress acting at its cross-section is equal to

• A. Zero
• B. $\frac{16T}{\pi d^3}$
• C. $\frac{32T}{\pi d^3}$
• D. $\frac{64T}{\pi d^3}$

Answer 1

The correct option is A Zero

Torsion produces shear only and no normal stress.
