Stress is defined as the force experienced by the object which causes a change in the object while a strain is defined as the change in the shape of an object when stress is applied.

Stress is measurable and has a unit while a strain is a dimensionless quantity and has no unit.

The words stress and strain are derived from the Latin words “strictus” and “stringere” which means “to draw tight” and “to bind tightly”, respectively.

Stress can occur in the absence of strain whereas strain does not occur in the absence of stress.
