Question

Driving to work one morning, you get a flat tire. When using the car jack, you apply 120N of force to the jack and the jack in turn applies 2000N of force to lift the car up. What is the mechanical advantage of the jack?

Answer 1

16.7

Step-by-step explanation:

Mechanical advantage is the ratio of the output force to the input force.

MA = Fout / Fin

MA = 2000 N / 120 N

MA ≈ 16.7
