A body subjected to strain a number of times does not obey Hook's law due to

A

Yield point

B

permanent state

C

elastic fatigue

D

breaking stress

Text Solution

Verified by Experts

The correct Answer is:
a
When a body is subjected to strain several times, then its length, goes on increasing rapidly i.e., the material of body flows like a viscous fluid and it acquires yield point after which it does not obey Hook's law.
