Why spring shows wrong reading after a long use?

Asked by prasantaratha.lic | 15th Jan, 2017, 11:26: AM

Expert Answer:

A spring is made up of a material which has some elasticity. Now, after prolong use the material loses its elasticity. Due, to this it does not regain its original configuarion after removal of force. Hence, it tends to show incorrect reading after a long use.
