Correct Stretch

Stress can be defined as the force applied to the object per unit area. The tensile stress is said to occur when an equal and opposite force is applied to the object. Tensile stress may cause a change in the length of the material in the direction of the applied force.

This force may cause the change in the shape of the object but the volume remains the same.

Example: Tensile stress is seen in the tug of war.
