What is the maximum value of deforming force upto which a material shows elastic property and above which the material loses it ?

  • A.Stress
  • B.Strain
  • C.Elasticity
  • D.Elastic limit

Answer: D

This is the elastic limit.

Up to it the body returns exactly to its original shape when the load is removed; beyond it a permanent set remains. It should not be confused with the breaking stress, which lies further along the stress-strain curve.
