Full Definition of EFFICIENCY. 1. : the quality or degree of being efficient. 2. a: efficient operation b (1) : effective operation as measured by a comparison of production with cost (as in energy, time, and money) (2) : the ratio of the useful energy delivered by a dynamic system to the energy supplied to it. 3.
Calculating Efficiency of Simple Machines. Efficiency is a measure of how much more work must be put into a machine than you get out of the machine.In the real world, the efficiency of a machinewill always be less than 100%. This means that a machine will never do work for you.f there was no friction, the best you could hope for is an efficiency of 100% meaning work in = work out. We can calculate efficiency by comparing work out to work in.Look below for an example. Efficiency = Work input / Work output x 100%. or we can calculate effiency by comparing TMA to AMA.
