3. Two tangents intersect at chainages 50.60 (50 chains and 60 links), the deflection angle being 61°. Calculate the necessary data for setting out a circular highway curve of 20 chains radius to connect the two tangents by the method of offsets from chords. Take peg interval equal to 100 links with length of the chain being 20 meters (100 links).

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.
