A simple machine is a mechanical device that changes the direction or magnitude of a force . [2] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage ) to multiply force. [3] A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the force. The ratio of the output to the input force is called the mechanical advantage. Usually the term refers to the six classical simple machines which were defined by Renaissance scientists: [4] Lever Wheel and axle Pulley Inclined plane Wedge Screw SCREW 1. a mechanical device for fixing one object to another, characterized by a spiral ridge cut on the external surface of a cylindrical rod of decreasing diameter towards its point.
