Two tangents converge at an angle of 30° And is connected by a reverse curve of equal radii. The direction of the second tangent is due east. The perpendicular distance of PC to the second tangent is 116.500 m. The bearing of the common tangent is S 40° E, and the central angle of the second curve is 50⁰°. a. Compute the central angle of the first curve Answer: 11= b. Common radius of the curve Answer: R= c. Stationing of PT if PC is at 10+620 Answer: Sta PT= m

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.
