What is a wedge?

A wedge is a piece of metal, wood, or some other material that has a thick end that is tapered to a narrow edge. It can be driven between two parts or objects to either pull them together, or separate them.

Mechanical Advantage

The mechanical advantage of a wedge depends on the slope, and width of the wedge. Ex: A short wedge may do the job faster, but it requires more force to move the object upwards. Unlike a longer wedge that wouldn't require as much force, but more time.


Billy has a wedge with a length of 15cm, and a width of 5cm. He wants to know the mechanical advantage of his wedge. What is the mechanical advantage?
