Meaning of MACHINE in English

MACHINE

I

Device that amplifies or replaces human or animal effort to accomplish a physical task.

A machine may be further defined as a device consisting of two or more parts that transmit or modify force and motion in order to do work. The five simple machines are the lever , the wedge , the wheel and axle , the pulley , and the screw ; all complex machines are combinations of these basic devices. The operation of a machine may involve the transformation of chemical, thermal, electrical, or nuclear energy into mechanical energy, or vice versa. All machines have an input, an output, and a transforming or modifying and transmitting device. Machines that receive their input energy from a natural source (such as air currents, moving water, coal, petroleum, or uranium) and transform it into mechanical energy are known as prime movers; examples include waterwheels , turbines , steam engines , and internal-combustion engines .
