Levers Explained. a lever is a simple machine consisting of a plank or a beam that can rotate freely about a fixed point. It has three important parts: Levers can help to lift. All early people used the lever in some form, for moving heavy. what is a lever? a lever is a simple device that works by changing the input force needed to do work and move something. Greek mathematician archimedes was the first to develop lever principles in 260 b.c. It is used for moving, lifting, or propelling objects. learn the basic principles and types of levers, the simple machines that can provide a mechanical advantage. It is perfect for lifting or moving heavy things. a lever is simply a plank or ridged beam that is free to rotate on a pivot. Some levers do this by magnifying the force. Find out how archimedes discovered the law of the lever and how it applies to everyday situations. lever, simple machine used to amplify physical force. A lever is a simple mechanism that can help make hard work easier to do.
