A pulley system used to lift car tires has a mechanical advantage of 8.1. If
you pull on the pulley with a force of 540 N, how much force does the pulley
exert on the tire?

Respuesta :

Answer:

4400 N

Explanation:

MA = Fout / Fin

8.1 = Fout / 540 N

Fout = 4374 N

Rounding to two significant figures, the force the pulley exerts on the tire is 4400 N.
