Question

With reference to Elasticity, define the following terms: 1. Stress 2. Strain

Answer 1

Explanation:

Stress is the internal resisting forces per unit area developed in the body against deformation. It is given by. f= P/A where P = load applied and A area of cross section. While strain is a dimensionless quantity defined as ratio of change in dimension to the original dimension.

❤⭐STRESS ⭐❤

• The restoring force by area is called stress .
• Stress = F/A
• Units : N/m^2 .

❤⭐STRAIN ⭐❤

• If we remove the forces on the a body , Of it can regain its original shape then this property is called strain.
• It is also ratio between change in dimension (shape) and orignal dimension of given body.
• Strain = change in direction / orignal in direction.
