Situation 4] Two tangents that intersect at an angle of 48°40' are to be connected by a compound curve consisting of a 4.1° curve and a 5.5° curve. If the tangent at the beginning of the curve to the point of intersection of the tangent is 110 m long, i. Compute the central angle of the first curve, 1. ii. Compute the central angle of the second curve, 12. ii. Compute the length of the tangent from the end of the 5.5°-curve to the point of intersection of the tangents. 4:37 PM

Q: Two parallel tangents, 10 meter apart, are connected by a reverse curve. The chord length from PC to…

A:

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.
