A lever is any simple machine that turns around a fixed point. There are three parts to a lever. They are fulcrum, effort and load. There are three classes of levers based on the position of the fulcrum. Examples of levers are scissors, bottle openers, wheelbarrow, see-saws, ice tongs, etc.

A wedge is a simple machine made up of two inclined planes to form a sharp edge. Note: A wedge is used to split things apart. The sharper the edge, the easier is the work.

A screw is an inclined plane that goes around a cylinder. It has ridges or threads that change the direction of force applied. Note: A screw holds things together through a longer distance with a stronger grip.
