Compressive strain is the shortening of an object in compression. Tensile strain is the enlongation of an object in tension. Shearing strain is a lateral deformation caused by a force which tends to move part of an object more than another. Compare to stress. The resistance of an object to external force.
Compressive stress develops as an object in compression resists being shortened.
Tensile stress develops as an object in tension resists being enlongated. Shearing stress develops as an object subject to shearing forces resists deformation. Compare to strain. A stable assembly of components which carries a load while resisting various applied stresses, and transfers the load though its foundation to the ground. Tension Stress characterized by pulling apart.
