A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance … See more The word "lever" entered English around 1300 from Old French: levier. This sprang from the stem of the verb lever, meaning "to raise".
