Question

8. A crate of bananas weighing 3000 N is shipped from South America to New York, where it

is unloaded by a dock worker. The worker lifts the crate by pulling with a force of 200 Non
the rope of a pulley system. What is the mechanical advantage of the pulley system?

Answer 1

Mechanical advantage = 15

Step-by-step explanation:

Given the following data;

Output force = 3000N

Input force = 200N

To find the mechanical advantage;

Mechanical advantage = output force/input force

Substituting into the equation, we have

Mechanical advantage = 3000/200

Mechanical advantage = 15
