Question

A helical spring is stretched by a force, the resultant strain produced in the spring is:

• A. volume strain
• B. shearing strain
• C. longitudinal strain
• D. all the above

Answer 1

Answer: (B)

shearing strain

Shear strain is defined as the strain accompanying a shearing action. It is the angle in radian measure through which the body gets distorted when subjected to an external shearing action.
When the force is applied on the helical spring the cross-section of the wire of the spring experiences torsion thereby establishing shearing strain in the material.
