Question

A car is rounding a circular curve of radius r on a banked turn. As the drawing indicates, there are two forces acting on the car, its weight mg and the normal force FN exerted on it by the road. Which force, or force component, provides the centripetal force that keeps the car moving on the circular path?

The horizontal component, FNsin? of the normal force. A car is rounding a circular curve of radius r on a banked turn. As the drawing indicates, there are two forces acting on the car, its weight mg and the normal force FN exerted on it by the road. Which force, or force component, provides the centripetal force that keeps the car moving on the circular path?

Explanation / Answer

centripital force is in horizontal direction. so the forces that are not perpendicular to horizontal , provides centripital force. mg is vertical , so it will not provide.

so FN forces;s component in horizontal direction. that is Fnsintheta

so

The horizontal component, FNsin? of the normal force.
