3.5 Wedge

A wedge is a double-inclined plane (both sides are inclined) that moves to exert a force along the lengths of the sides.

— The force is perpendicular to the inclined surfaces, so it pushes two objects (or portions of a single object) apart.
— Axes, knives, and chisels are all wedges. .
— The common "door stop wedge" generates large frictional forces on the wedge surfaces to provide friction for keeping doors open.
