1. Wedge wedge A wedge is triangular shaped round tool, a compound and portable inclined plane and one of the six classical simple machine. It can be used to separate two objects or portions of an object, lift an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width. Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle

2. How the wedge is used These early wedges were stone hand-axes, and their sharp edges let people cut a hunk of meat off a gazelle to eat, or cut branches for firewood. Probably people also used wooden wedges to split bigger pieces of wood into smaller pieces.

3. Benefits of wedge Wedge is a very useful machine because it allows us to cut and split things easily. E.g. wood, meat etc. wedges are very useful in daily life E.g. knife, fork, axe etc.
