Along a turn, the outer edge of a road is lifted up such that it is higher than the inner edge and the surface of the road looks like a slightly inclined plane. This is called banking of a road. The angle made by the surface with the horizontal, i.e. the angle of inclination, is referred to as the banking angle. WebJul 25, 2024 · Consider a car driving along a curvy road. The tighter the curve, the more difficult the driving is. In math we have a number, the curvature, that describes this "tightness". If the curvature is zero then the curve looks like a line near this point. While if the curvature is a large number, then the curve has a sharp bend. nisbets soup bowls
