Simply put, levers are machines used to increase force. We call them “simple machines” because they have only two parts — the handle and the fulcrum. The handle or bar of the lever is called the “arm” — it’s the part that you push or pull on. The “fulcrum” is the point on which the lever turns or balances.
A hammer is an example of a lever. A lever is a simple machine consisting of a bar that rotates around a fixed point called the fulcrum.
