A machine is any man-made physical system with various moving parts that use energy to perform work. Machines reduce or replace the muscular or mental work of humans in accomplishing tasks. Simple machines include the lever, pulley, wheel and axle, wedge, and screw. Complex machines include clocks, computers, washers and dryers, pipe organs, locomotives, refrigerators, and automobiles.

A machine is a tool containing one or more parts that uses energy to perform an intended useful action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often (but not necessarily) motorized.
The "six classical simple machines" of physics (lever, wheel and axle, pulley, inclined plane, wedge, screw) are the basic parts of mechanical machines, but machines can also include electronic, hydraulic, pneumatic, optical, thermal, etc. parts too.
A Turing machine can be built to accept the language defined by the keyword.
resistence
effort
The term defined as the force applied to a machine is input force. This force is the effort that a person or system applies to a machine in order to make it work and perform its intended function.
A Wedge
It is defined as a device, which overcome resistance at a point when some force is applied to it at some other convenient point.

A wheel and an axle can be defined as a simple machine.
George H. Mealy presented the concept of a finite-state machine that became known as the Mealy machine in a 1955 paper, "A Method for Synthesizing Sequential Circuits." This machine differs from a Moore machine in that rather than the outputs being defined by the current state, the outputs are defined by both the current state and the current inputs.
Originally, Norbert Weiner defined it as the study of "Control and communications in animal and machine." Nowadays, it's usually defined as the study of regulatory systems.
A screw is defined as an inclined plane wrapped around a cylinder.
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
