Question

Shaft is subjected to which of the following stresses?

• A. Bending
• B. Torsional
• C. Both Bending and Torsional
• D. Tensile

Hint:

Whenever a shaft transmits torque and carries side loads (like pulleys or gears), always consider both torsion and bending stresses.

Answer 1

The Correct Option is C

A shaft in a mechanical system typically transmits torque, resulting in torsional shear stress.
Additionally, when the shaft is subjected to transverse loads (such as from gears or pulleys), it also experiences bending stress.
Hence, a shaft generally undergoes both torsional and bending stresses simultaneously.
Tensile stress is not a primary mode of loading for shafts.
