Question

What is the basic difgerence between elastic fatigue amd elastic after effect?

Answer 1

When a elastic body is stretched and applied deforming force is removed then the body is expected to return to its original configuration instantaneously. But sometimes some materials take some time to return to its original configuration. This temporary delay in achieving its original configuration is termed as elastic after effect. This elastic after effect is very short for quartz fiber. But elastic after effect is more for glass. Therefore quartz fiber is used in galvanometer coil.

Answer 2

Hey!!

Here is your answer:-

✴️ Elastic after effect = The delay ofcertain substances in regaining their original shape after being deformed within their elastic limits. Elastic fatigue= The temporary loss of elasticproperties because of the action ofrepeated alternating deforming forceis called elastic fatigue.
