Definition of Machine and Simple Machine

An arrangement by which work can be done conveniently on a load or against a resistance is known as machine 

A simple machine is a machine in its simplest form. They are devices that use energy to do work. The work is being done by the machine when a small effort is used to overcome a large resistance.

A machine can be defined as a tool or devices that allows a force (or effort) applied to one point to overcome a resisting force (or load) at another point.

Simple machine can be classified into different categories namely the lever, the pulley, the inclined plane, the wedge, the wheel and axle, the screw, the hydraulic press.
