How to Calculate the Mechanical Advantage of a Wedge – formula

Last updated on May 18th, 2023 at 03:08 pm

A wedge is a simple tool in the shape of a triangle. In other words, a wedge is simply two inclined planes back to back. 
Figure 1 shows the simple formulas for calculating the IMAs of these machines.
The mechanical advantage formula for a wedge is dependent on its geometry: IMA = L/t

MA of a wedge = L / t

Wedge can be used to split an object into two parts or to lift heavy objects. Knives and axe heads are examples of wedges.
