- In general, any combination of bodies so connected that
their relative motions are constrained, and by means of
which force and motion may be transmitted and modified, as
a screw and its nut, or a lever arranged to turn about a
fulcrum or a pulley about its pivot, etc.; especially, a
construction, more or less complex, consisting of a
combination of moving parts, or simple mechanical
elements, as wheels, levers, cams, etc., with their
supports and connecting framework, calculated to
constitute a prime mover, or to receive force and motion
from a prime mover or from another machine, and transmit,
modify, and apply them to the production of some desired
mechanical effect or work, as weaving by a loom, or the
excitation of electricity by an electrical machine.
Note: The term machine is most commonly applied to such
pieces of mechanism as are used in the industrial arts,
for mechanically shaping, dressing, and combining
materials for various purposes, as in the manufacture

Wikipedia Meaning and Definition on 'Machine'
A machine is a device that uses energy to perform some activity. In common usage, the meaning is that of a device having parts that perform or assist in performing any type of work. A simple machine is a device that transforms the direction or magnitude of a force without consuming any energy. The word "machine" is derived from the Latin word machina,
Historically, a device required moving parts to be classified as a machine; however, the advent of electronics technology has led to the development of devices without moving parts that many refer to as machines—the computer being the most obvious example.
"Engines" are machines that convert heat or other forms of energy into mechanical energy. For example, in an internal combustion engine the expansion of gases caused by the heat from an exothermic chemical reaction results in a force being applied to a movable component, such as a piston or turbine blade. An engine is often considered part of a larger machine, such as an automobile or an aircraft.[See more about Machine at Dictionary 3.0 Encyclopedia]
