When you learn to drive, the most difficult control to master is that of steering.Do you know there are some amazing physics and mechanisms beneath the steering wheel, which keeps the vehicle on the right track without any skidding of the wheels.

This video will demonstrate why we need such mechanisms for steering, and how they work. We will also understand the workings of power steering mechanisms.Power steering is a device that helps drivers steer by augmenting steering effort of the steering wheel.
Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly.

Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system.Electric power steering systems use electric motors to provide the assistance instead of hydraulic systems.
