Mechanical efficiency
From Wacklepedia - The Free Encyclopedia
In
physics,
mechanical efficiency is the effectiveness of a
simple machine.
The formula for finding efficiency is,
- Efficiency = AMA ?IMA
where
AMA equals
actual mechanical advantage and
IMA equals
ideal mechanical advantage.
Efficiency is measured as a percentage. The efficiency of an ideal machine is 100%. Therefore, all real machine efficiencies are less than 100%.
