The force applied on unit area to produce any change in the volume or length of a body is called:
Correct answer: B. Stress
- A. Strain
- B. Stress
- C. Elasticity
- D. Equilibrium
Explanation
When the force applied produces a change in length or volume of the object then is it called stress, otherwise the term strain is used.

About Deformation and Elasticity
Deformation and elasticity describe how solids change shape or volume under an applied force and return to their original form when the force is removed. Work includes stress, strain, Hooke’s law, elastic limit, Young’s modulus and elastic potential energy, while elastic deformation must be distinguished from permanent plastic deformation.
