In the alongside figure of two pulleys shown a system in which one pulley is fixed and … mechanical advantage and efficiency of the…
If there are n movable pulleys connected to a fixed pulley, then velocity ratio is
V.R = 2n
Velocity ratio of the system = 2.
Mechanical Advantage = Load/Effort = 1000/600
Efficiency = M.A./V.R.
= (5/3)/2 = 5/3 x 2 = 5/6
