Compression is a force that tends to squeeze or crush a material, as shown in Figure

Shear is a force that tends to slide one face of the material over an adjacent face.
For example
-a rivet holding two plates together is in shear, if tensile force is applied between the plates

Tension is a force that tends to stretch a material, as shown in Figure.
For example,
-the rope
or cable of a crane carrying a load is in tension
-rubber
bands, when stretched, are in tension

-when a nut is tightened, a bolt
is under tension
A tensile force, i.e. one producing tension,
increases the length of the material on which it acts
