Levers are simple machines used to lift weights. First let's learn some terms you will need to know. A load is the thing you're lifting. A fulcrum is the thing that makes the load lighter. An effort is the person pushing to make the objects move. ... There are three different types of levers as shown in these three pictures...

There are three types, or classes of levers. These classes are based on the position of the effort force, resistance force, and fulcrum. ; First-class levers have the fulcrum between the effort force and the resistance force.
