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.

Question

Problem 5: The clearance to an obstruction is 10 m and the desired sight distance when rounding
a horizontal curve is 180 m. Determine the minimum radius of the curve required assuming that the
sight distance is less than the length of the curve.
