Question # 1

Define elastic limit and Yield point.

  • Ans 1: The greatest stress that a material can endure without any permanent deformation is called elastic limit.This kind of behavior is called elasticity.
    Yield point: The point on the stress-strain curve beyond which if stress is further increased then permanent deformation takes place in the given specimen.This is called yield point.

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.
