What is Stress and strain explain briefly

Question

Accepted Answer

Stress is the force applied to a material, while strain is the resulting deformation or change in shape of the material.

Stress is a measure of the internal forces within a material that resist deformation.
Strain is the measure of the amount of deformation or change in shape that occurs in a material when subjected to stress.
Stress and strain are related through the material's elastic modulus, which describes its stiffness.
Stress is typically measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).
Strain is a dimensionless quantity and is often expressed as a percentage or in units of length per unit length.

Accepted Answer

Stress is internal resistance offered by body against deformation and strain is ratio of difference between deformed shape to actual shape
