It is necessary to lay out a simple curve by deflection angles. The curve is to connect two tangents with an intersection angle of 320 and a radius of 240.00 meters. Compute the deflection angles to each full stations on the curve if the transit is set up at PC which is at Station (5 + 767.20m). Find the station of PT. Illustrate the figure and tabulate the results.
3 Horizontal curves You are asked to design a 5-degree horizontal curve with an intersection angle at the center equals 60°15'. The station of point of curvature is 155 + 26.5 ft. Calculate the following: A. Length of the curve B. Station of the point of tangency (PT) C. For first two whole stations next to PC, calculate the degree of deflection from the PC and chord length from the previous point along the horizontal curve.
