WHAT IS STRESS?

Stress is defined as force per unit area within materials that arises from externally applied forces, uneven heating, or permanent deformation and that permits an accurate description and prediction of elastic, plastic, and fluid behaviour.

WHAT IS STRAIN?

Strain is the amount of deformation experienced by the body in the direction of force applied, divided by the initial dimensions of the body.

This Video is Demonstrating how to carry out calculations involving Simple Stresses and Strains.
