Compressive strength is an effective way of measuring how much load a surface or material can bear. The test for this sort of strength is performed by exerting force downward on top of the object, paired with an equal and opposite force exerted upward on the bottom.

Tensile and compressive force acts perpendicular to the surface of the object. That is why these are called direct stresses. One has to recognize whether the stresses are tensile or compressive by the direction of forces acting on the object because this is what the main difference between them. Tensile and compressive strains
