Answer:
A wheel and axle may either increase or decrease the input force, depending on whether the input force is applied to the axle or the wheel. ... Because the output force is less than the input force, the mechanical advantage is less than 1. However, the wheel turns over a greater distance, so it turns faster than the axle.
If you apply a force to the wheel (the handle), the wheel spins and multiplies the effort to make the output force of the axle (shaft) greater.
The drive shaft, which on most cars runs the length of the vehicle to the rear wheels, turns as the combustion engine burns gasoline. The turning drive shaft sends power to the rear axle and wheels, which cause them to turn as well, moving the car forward
There some moments when the steering wheel becomes stiff and hard to turn. From irregular servicing, lack of fluid oil to low tyre pressure or bad wheel alignment, any of these could be the cause
