Simple Machines by Richard Roberts

Levers For an example a second class lever is a wheel barrel. You use your hands as the effort force. The load is anything you want to move or carry. The fulcrum is the wheel or wheels.

Inclined Planes Inclined planes are ramps.Inclined planes help you lift heavy objects. Inclined planes are used in home movers companys.

Wedge A wedge is two inclined planes together. A ax is an example of a wedge.

Scissors A scissor is a compound machine. A scissor are two wegdes , that are arranged as two first class levers.

Pulley A pulley makes things easier to lift almost like a inclined plane. There are three types of pulleys. Fixed,moveable ,and fixed moveable pulleys.
