2. The power steering in an automobile has a mechanical advantage of roughly 75. If the input force on the steering wheel is 49 N, what is the output force that turns the car's front wheels?

3675N

Explanation:

A mechanical advantage measures the amplified force taken by the whole mechanical system.

It gives the ratio between the force applied to the load and the force needed to overcome the given force. It has no unit because the two ratio quantities are  force.

Mechanical advantage is  defined as the force exerted by the machine to the for force applied on it.

Mechanical Advantage =

MA= output force/input force

Wherein,

MA is the mechanical advantage, =75

Input force= 49N

Output force ?

MA=output force /input force

75=x/49

OUTPUT FORCE = 75X 49 = 3675N
