Question

The property of a material due to which shape is changed permanently is known as:

• A. Elasticity
• B. Plasticity
• C. Ductility
• D. None of the above

Answer 1

The correct option is B Plasticity

The property of a body to regain its original shape when the deforming force is removed from it or to oppose the change in its original shape is called elasticity.

Plasticity is the property of a material not to regain its original shape when the deforming force is removed, i e. a deforming force changes the shape of material permanently.

Ductility is commonly defined as the ability of a body to be stretched into wires.

Hence, option B is correct.
