Mechanical advantage of a pulley system is the ratio of load to effort. That is,

M.A = Load/Effort

We have,

Effort = Force applied = 50 lb

Load = Weight lifted = 500 lb

Substituting the values we get,

M.A = [tex] \frac{500}{50} [/tex] = 10

Mechanical advantage of the given pulley system is 10.
