on the wedge. This is the mechanical advantage of the wedge. This formula for mechanical advantage applies to cutting edges and splitting operations, as well as to lifting.

Note that since wedge explicitly relies on force of resistance on both sides of the wedge to deliver the force multiplier and achieve an equilibrium, the situations when one of the sides of the wedge is limited in the amount of force of resistance it can deliver is no longer a classical wedge and should be considered separately.

They can also be used to separate
