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

• Stress is measured in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m²).

• Strain is measured as a ratio of the change in length or shape of the material to its original length or shape.

• The relationship between stress and strain is described by the materia...read more
