Question

only what is lever?

​

Answer 1

Explanation:

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.
