The azimuth from south of the tangent from PC to Pl is 223 degrees and PI to PT is 323 degrees. The central angle of the first curvę is 41 and the tangent of the first curve measures one third of the distance V1 to V2.

Q: The offset distance of the simple curve from PT to the tangent line passing through the PC is equal…

A: We knowTangent length = Offset×sinIT=120.2×sin50T=156.9mso,T=RtanI2156.9m=Rtan502R=334.5m

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.
