Explain why large trucks have bigger steering wheels than small trucks or cars?

The rotation of the steering shaft drives the turning of the wheels, and buses and large trucks have wheels which are significantly more massive than cars' and light trucks', requiring more torque on the steering shaft to turn the wheels. The larger steering wheel gives a mechanical advantage in turning the steering shaft; a longer moment-arm from the application of force by the driver on the steering wheel results in a larger torque on the steering shaft from the same force applied.

How does an power steering works?

Power steering is used to help the driver turn the wheel. Power steering is powered by a fluid held within the reservoir, where you put the power steering fluid into. Then, the power steering pump takes over. That pumps the steering fluid to the steering gearbox, which flows to the valve body unit (kind of like a crank). Once you turn the wheel to the left or to the right, the computer tells the steering fluid to push against the crank to make the wheels move, taking less stress off the driver. You usually find power steering in bigger vehicles, such as pick up trucks, big rigs, bigger cars, etc. You won't find it in smaller cars because it's already easy to turn.
