A simple machine is a mechanical device that changes the direction or magnitude of a force. [1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. [2] Usually the term refers to the six classical simple machines that were defined by Renaissance scientists: [3] [4 ...
The hand axe is the first example of a wedge, the oldest of the six classic simple machines, from which most machines are based. The second oldest simple machine was the inclined plane (ramp), [6] which has been used since prehistoric times to move heavy objects.

Coinciding with the release of the remastered original episodes of The Secret Life Of Machines (see below), Tim Hunkin began a self-produced spiritual successor called The Secret Life of Components. [8] It explored some of the individual parts that so often make up the appliances and machines that were the focus of the original series.
Like the other simple machines a screw can amplify force; a small rotational force on the shaft can exert a large axial force on a load. The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force).
Machine element or hardware refers to an elementary component of a machine. These elements consist of three basic types: These elements consist of three basic types: structural components such as frame members, bearings , axles , splines , fasteners , seals , and lubricants ,
An early wheel made of a solid piece of wood. A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle bearing.The wheel is one of the key components of the wheel and axle which is one of the six simple machines.
