Simple curve R = 280 m I = 50° To be replace by another curve having 80 m spirals at its ends such that the point of tangency shall be the same. Compute for the radius of the new circular curve.

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
