Mechanical Advantage
The lever is an example of a simple machine. Machines are used to multiply
force (or speed).
For example, the lever below shows that the effort force
has been multiplied by 5.
20 Ib
100 1b
(1)
Because the effort has been mutliplied by 5, we say that the lever has an
actual mechanical advantage of 6orce (AMA-) of 5.
Thus, we see that the
definition of actual mechanical advantage of force is the resistance divided
by the effort.
