Mechanical advantage is the ratio between the output force and the input force. It
is a number that shows the difference between the input force and the output
force in a mechanism. If the number is greater than 1, then the output force is
bigger ...
That is, Many machines, like the bottle opener, have a mechanical advantage
greater than one. When the mechanical advantage is greater than one, the
machine increases the force you apply. We can calculate the mechanical
advantage of a ...

Mechanical advantage (MA) is the ratio of the in-lever arm to out-lever arm and
also the ratio of the out-force to the in-force (MA = Lin/Lout = F(m/Fin). A lever
system in which an Fin of 5N results in an Follt of 10N would have a mechanical ...
