Answer:

Load = 1680 N

Step-by-step 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=(load)/(effort)


11.2=(load)/(150\ N)

Load = 1680 N

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