In some cases, the main goal is to keep things attached/aligned and resist their ability to slide apart. This function (and force) is known as shear.

WebJust like stress, there are two types of strain that a structure can experience: 1. Normal Strain and 2. Shear Strain. When a force acts perpendicular (or "normal") to the surface of an object, it exerts a normal stress. When a force acts parallel to the surface of an object, it exerts a shear stress. Let's consider a rod under uniaxial tension.
