1. machine


Sinonimi: political machine | simple machine

ETYM French, from Latin machina machine, engine, device, trick, Greek, from mechane means, expedient. Related to Mechanic.
1. Any mechanical or electrical device that transmits or modifies energy to perform or assist in the performance of human tasks.
2. An intricate organization that accomplishes its goals efficiently.
3. An efficient person.
4. A group that controls the activities of a political party; SYN. political machine.
5. A device for overcoming resistance at one point by applying force at some other point; SYN. simple machine.
Device that allows a small force (the effort) to overcome a larger one (the load). There are three basic machines: the inclined plane (ramp), the lever, and the wheel and axle. All other machines are combinations of these three basic types. Simple machines derived from the inclined plane include the wedge, the gear, and the screw; the spanner is derived from the lever; the pulley from the wheel.
The principal features of a machine are its mechanical advantage, which is the ratio of load to effort, its velocity ratio, and its efficiency, which is the work done by the load divided by the work done by the effort; the latter is expressed as a percentage. In a perfect machine, with no friction, the efficiency would be 100%. All practical machines have efficiencies of less than 100%, otherwise perpetual motion would be possible.
