What is mean by stress.and strain

Question

Accepted Answer

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

Stress is the external force or load applied to a material.
Strain is the measure of deformation or change in shape that occurs in response to stress.
Stress and strain are related through the material's elastic properties.
Stress is typically measured in units of force per unit area (such as pounds per square inch or pascals).
Strain is a dimensionless quantity and is often expressed as a percentage or in terms of elongation or compression.
For example, when a metal rod is subjected to a tensile force, it experiences stress, and the resulting elongation or deformation is the strain.

Accepted Answer

Stress is mean by force into the particular area of the matter                strain is mean by change in length by original length is called strain
