Elasticity - Question 1

The property of the material due to which it regains its original shape or size when the load is removed is called:

Detailed Solution for Elasticity - Question 1

Elasticity:

  • When an external force is applied to a rigid body there is a change in its length, volume (or) shape. When external forces are removed the body tends to regain its original shape and size.

  • Such a property of a body by virtue of which a body tends to regain its original shape (or) size when external forces are removed is called elasticity.

Plasticity:

  • Plasticity is the ability of a material to undergo permanent deformation.

​Viscosity:

  • The viscosity of a fluid is a measure of its resistance to deformation at a given rate.
  • Viscosity describes a fluid’s resistance to flow.

EXPLANATION:

  • Elasticity is defined as the property of a body by virtue of which a body tends to regain its original shape (or) size when external forces are removed.
  • Hence, option 1 is correct.
