A machine is defined as any device that accomplishes work using
mechanical or electrical energy. Machines manage energy and
power to transform the magnitude and direction of force directed
towards work. Increasingly insignificant to industry market and
equipment demand, simple machines qualify as classical machines,
but are rarely included in industry groupings. More significant
machines to industry are clocks, compressors, expanders, turbo
machinery, pumps (including centrifugal, positive displacement),
internal and external combustion engines, reciprocating engines,
other heat engines, turbines, and airfoils (wings, propellers,
rudders). The advent of electronics and information technology
(IT) led to the emergence of numerous devices and products
without moving parts (mechanical work) that are called machines,
such as devices with integrated circuitry (IC) (computers),
televisions, radio, lasers and various industrial tools using
electricity and electromagnetic radiation. Industrial robots and
