Concept explainers

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

The radius of the first curve passing PC is equal to 265 m. while of the second reversed
curve is 470m long. If the central angle of both curves is 15°, determine the parallel
distance between two tangents.
