WebJul 30, 2024 · Ideal Mechanical Advantage (I.M.A.) & Actual Mechanical Advantage (AMA) The ratio of load to the effort is known as mechanical advantage. ∴ Mechanical advantage (M.A) =Load (W)/Effort (E). If a large load is lifted with small effort, then the mechanical advantage is greater than one.

In a real machine, the AMA is always the IMA.

WebJul 2, 2015 · Explanation: The Actual Mechanical Advantage AMA is equal to: AM A = F out F i.n that is, the ratio between the output and input force.
