They can't uless some parts are hidden from inspection.
Two machines may appear identical and yet not have the same actual mechanical advantage because of the different input and output force.
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
Perfect efficiency
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 and estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less. Sources: Science teacher ------------------------------------------------------------------------------------------------------------------ The answer above is incorrect. The ideal mechanical advantage (IMA) is usually less than the mechanical advantage (MA) in a given machine because of the friction acting on the machine. There will always be some frictional resistance that increases the effort necessary to do the work.
I haven't gotten around to repeating it yet. I've been so busy, had so much homework, the dog ate it, etc.
No units. It is a ratio
The actual mechanical advantage is usually less, due to losses.
we can save our time by using machines and a machine can perform the work of hundred men.

Mechanical Advantage = distance moved at input / distance moved at output
Mechanical Advantage: F(out)/ F(in) Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do
IMA- Ideal mechanical advantageAMA- Actual mechanical advantage
Depending on the context , it might mean " medical". Mechanical = 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.
You can grip things tightly with them.

The ratio of resistance force to effort force is a mechanical advantage.
