If the distance from the input force to the fulcrum is greater than the
distance from the output force to the fulcrum, the ideal mechanical
advantage is greater than 1.
IMA = d in / d out.
Explanation:
- The distance between the input force and the fulcrum changes by sliding the weight across the beam. To balance the beaker, the output force is applied.
- The formula for the ideal mechanical advantage of a lever is given as
- The ratio of the distance from input force to fulcrum to the distance from output force to the fulcrum is known as the Ideal Mechanical Advantage (IMA).
IMA= distance from input force/distance from output source.
- The IMA is greater than 1 if the distance from the input force to the fulcrum is greater than the distance from the output force to the fulcrum.
