Shaft is subjected to which of the following stresses?

ABending

BTorsional

CBoth bending and torsional

DNone of these

Answer:

C. Both bending and torsional

Read Explanation:

Shafts are subjected to both bending and torsional stresses. They are designed for strength and rigidity, considering the presence of shock and cyclic loads, and the deflection of long shafts under bending moment and torque. Failure starts from the point of stress concentration.
