Question

explain lever mechanisms

Answer 1

On the basis of the location of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage.

Answer 2

A first-class lever is a lever in which the fulcrum is located between the input effort and the output load. In operation, a force is applied (by pulling or pushing) at one end of which causes the lever to swing about the fulcrum, overcoming the resistance force on the opposite side.
