In a pulley system, if an input force of 100 N is used to lift a load of 500 N, what is the mechanical advantage?
The mechanical advantage of a pulley system is calculated by dividing the load force (output force) by the effort force (input force).
In this case, the load force is 500 N and the input force (effort force) is 100 N.
Mechanical Advantage = Load / Effort
Mechanical Advantage = 500 N / 100 N = 5
Therefore, the mechanical advantage of the pulley system is 5.
