The fulcrum,or pivot point

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
First Class Levers
An example of this type is a seesaw. The load is the person that goes up, and the effort applied is the weight of the person that goes down. The fulcrum is in the center in between them.

A seesaw is a lever since the fulcrum or the support lies in the middle. When the person sitting on one end(effort), applies force,the load or the other person rises, making it a lever.

The bar in the center. This is called the fulcrum. The distance on either side of the fulcrum determines the multification factor of force. If you have two feet of length on the downside of the fulcrum and one foot on the upside you will be able to lift 100 pounds with only fifty pounds of force thus a 2 to 1 ratio, ignoring any friction.

The same thing that makes a lever a seesaw.

A seesaw is a lever because it has a central-based fulcrum.
