Efficiency = Mechanical advantage/Velocity ratio.
So for ideal machines efficiency=1.
So for ideal machines efficiency=1.

Efficiency is one only when mechanical advantage equals velocity ratio.

Its a ideal machine. So its efficiency equal to 1 (100%).

Mechanical advantage is similar to the law of the lever.
For an ideal m/c. MA = OUTPUT TORQUE/INPUT TORQUE = INPUT SPEED/OUTPUT SPEED.
For an ideal machine, we are considering that friction and wear of machine are negligible.
So MA is 1.
