Q: The property by virtue of which a deformed body springs back to its original position after removing the external force is known as
  • A. Plasticity
  • B. Elasticity
  • C. Ductility
  • D. Tenacity
Correct Answer: Option B - Elasticity :- It is the property of body by the virtue of which it deforms by the application of deforming force and returns original shape after removal of deforming force. Elastic limit is the point up to which if the load is removed, original volume and shape are regained. Plasticity :- It is the property of body by the virtue of which it deforms permanently and never regain original shape after removal of deforming force. Material those show plasticity are called plastic materials.
