In front wheels can be turned to left and right by steering system so that the
vehicle can be steered. The steering wheel is placed in front of driver. It is
mechanically linked to the wheels to provide the steering control. The primary
function of the steering system is to provide angular motion to front wheels so that
vehicle can negotiate a turn. It also provides directional stability to vehicle when
the vehicle moves ahead in straight line. Now-a-days, many vehicles are equipped with power steering which uses pressure
of a fluid to reduce steering effort. When driver turns the steering wheel, a
hydraulic mechanism comes into play to provide most of the effort needed to turn
the wheel.
