Question # 1

Distinguished between elasticity and plasticity.

  • Ans 1: Elasticity: In deformed crystalline solid,the atoms return to their equilibrium position after the removal of external force.This ability of the body to return to its original shape is called elasticity.
  • Ans 2: Plasticity:If the stress is increased beyond elastic limit,the specimen becomes permanently deformed.This is called plasticity.
