Ideal mechanical advantage would be from a device with the assumed probability that there is no friction, wear or flexion. It is the ratio of the force put out (load) to the effort (force put into the machine).

Actual mechanical advantage takes into consideration of friction, wear and flexion. It is the ratio of the effort output and the effort input.
