1.Stress is defined as a force that can cause a change in an object or a physical body while strain is the change in the form or shape of the object or physical body on which stress is applied.
2.Stress can occur without strain, but strain cannot occur with the absence of stress.
3.Stress can be measured and has a unit of measure while strain does not have any unit and, therefore, cannot be measured.
4.Strain is an object’s response to stress while stress is the force that can cause strain in an object.
5.Stress comes from the Latin word “strictus” which means “to draw tight” while “strain” comes from the Latin word “stringere” which means “to bind tightly.”
