Question

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?

Answer 1

$${\rm Ideal \:mechanical\: advantage}=\frac{F_{\rm output}}{F_{\rm input}}=75$$

$$F_{\rm output}=75F_{\rm input}=75\times 49\:\rm N=3675\:\rm N.$$
