A simple curve of 800 m radius has been laid out connecting two lines with a deflection angle of 42°. It is decided, for construction reasons, that the midpoint of the curve must be moved 5 m towards the center, i.e, away from the intersection point. The alignment of the tangents is to remain unchanged. a. radius of the new curve b. distances from the intersection to the new tangent points c. length of the curve

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.
