Levers have a straight part that moves when a force is applied to it.
The point on the lever that does not move is called the fulcrum . When you hold a rake, one of your hands is above the other. The fulcrum is located where your upper hand holds the rake's handle. You move the rake by pushing and pulling on the rake's handle with your lower hand. The teeth of the rake then move the leaves.
