IMA- Ideal mechanical advantageAMA- Actual mechanical advantage
Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.
Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

No, the ideal is without friction.
At perfect 100% efficiency, the Actual Mechanical Advantage should equal the Ideal Mechanical Advantage.
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
