What is difference between stress and strain

Question

Accepted Answer

Stress is the force applied to an object, while strain is the deformation or change in shape that occurs due to stress.

Stress is an external force applied to an object, while strain is the internal response of the object to that force.
Stress is measured in units of force per unit area, while strain is measured in units of length per unit length.
Stress can cause strain, but strain can also occur without stress if the object is subjected to a change in temperature or humidity.
Examples of stress include tension, compression, and shear, while examples of strain include elongation, compression, and bending.
Stress and strain are related by the material's modulus of elasticity, which describes how much the material will deform under a given amount of stress.
