Question

A pulley system used to lift car tires has a mechanical advantage of 11.2. If you pull on the pulley with a force of 150 N, how much force does the pulley exert on the tire?

Answer 1

1680 is the answer i got because i did this problem in apex

Answer 2

Answer:

Load = 1680 N

Explanation:

Mechanical advantage of the pulley system, MA = 11.2

If a person pull on a pulley with a force of 150 N we have to find the amount of force the pulley exert on the tire. Mechanical advantage of a pulley system is given by the ratio of load to the effort force i.e.

$IMA=\dfrac{load}{effort}$

$11.2=\dfrac{load}{150\ N}$

Load = 1680 N

Hence, the force the pulley exert on the tire is 1680 Newtons.
