Answer 2

The variation of shear stress in a circular shaft  subjected to torsion is yield stress.

Explanation:

• Shear stress is a force that tends to cause distortion in an object.
• This force is produced along the plane or planes that are parallel to the implied stress.
• The stress produced by this phenomenon is of great significance as it produces earthquakes.
• The movement in other objects is also caused by shear stress.
• Some objects return to the original position once the stees is removed while some objects do not.
