Question

Define stress and strain?

Answer 1

Answer:

When deforming forces act on an object, they can change the object’s shape. The main difference between stress and strain is that stress measures the deforming force per unit area of the object, whereas strain measures the relative change in length caused by a deforming force.

★Stress

In a medical or biological context stress is a physical, mental, or emotional factor that causes bodily or mental tension.

★Strain

Strain is a measure of material deformation in response to an applied force (or stress). Strain is often incorporated into a ratio of, stress divided by strain to give material moduli, such as Young's modulus and the bulk modulus.
