Levers are one of the basic simple machines, along with wedges, pulleys, screws, inclined planes and the wheel and axle. Every gadget or machine around us is made up of one or more of these simple machines. A lever is a rigid bar that pivots at a point called the “fulcrum” and is used to move things. The fulcrum can be anywhere along the lever. The thing that you are moving is called the “load,” and the force applied on the lever is simple referred to as the “force.” A seesaw is a good example of a lever that has the fulcrum in the middle. The riders take turns being the load or the force, depending upon whether they are pushing up or gliding down. You will need to know the three types of levers. They are called first, second, and third class levers. First class levers have the fulcrum in the middle, as in a seesaw. Second class levers have the fulcrum at one end, the force at the other end and the load in the middle. A good example of a second class lever is a wheelbarrow. Third class
