Ideal machine is the machine in which friction is zero so input is equal to output so mechanical efficiency is 100% or 1.
Here mechanical efficiency is the ratio of mechanical advantage to the velocity ratio.
So MA=VR.
Here mechanical efficiency is the ratio of mechanical advantage to the velocity ratio.
So MA=VR.
