efficiencyor mechanical efficiencyIn mechanics, the measure of the effectiveness with which a system performs. It is stated as the ratio of a system's work output to its work input. The efficiency of a real system is always less than 1 because of friction between moving parts. A machine with an efficiency of 0.8 returns 80% of the work input as work output; the remaining 20% is used to overcome friction. In a theoretically frictionless, or ideal, machine, the work input and work output are equal, and the efficiency would be 1, or 100%. mechanical efficiency [mi′kan·ə·kəl i′fish·ən·sē] (mechanical engineering) In an engine, the ratio of brake horsepower to indicated horsepower.

A further 2% gain is achieved as a result of the system's greater mechanical efficiency, she added. The current method uses a crude measure: the heart's mechanical efficiency at pumping blood. Maybe that has something to do with that one being thoroughly believable, while this giant robot, for all its mechanical efficiency, just isn't very. |
