What is a banked curve?

A banked curve is a type of curve found on roads, highways, and race tracks that is designed to allow vehicles to travel around the curve more safely and efficiently. The curve is sloped at an angle, with the outer edge of the curve raised higher than the inner edge. This slope helps to counteract some of the centrifugal force experienced by a vehicle as it goes around the curve.

The angle of banking on a curve is typically calculated to ensure that the force of gravity helps to keep the vehicle in place on the curve, rather than pushing it outward. This can reduce the amount of friction needed between the tires and the road, allowing the vehicle to travel at higher speeds around the curve without skidding or slipping.

Banked curves are commonly used in racing circuits and on highways with high-speed limits, as they can help improve safety and reduce the likelihood of accidents caused by vehicles losing control on sharp curves. Additionally, they can also help improve the overall flow of traffic by allowing vehicles to navigate curves more efficiently.

Overall, banked curves are an important feature of roadway design that help to enhance safety and efficiency for drivers traveling around curves at high speeds.
