Two tangents converge at an angle of 30° and is connected by a reverse curve of equal radii. The direction of the second tangent is due east. The perpendicular distance from PI1 to PI2 is 159.5 m. The central angle of the second curve is 57°. Determine the radius of the curves.

A compound curve has the following data. I1 = 38  D1 = 4 12 = 22 D2 = 5 1.) Determine the length of the first curve 2.) Determine the length of the common tangent.

Three simple curves are connected to each other such that the fırst and the second form a compound curve. While the second and the third form a reversed curve. The distance between the point of curvature and the point of tangency of the compound curve (which is also the point of reversed curvature of the reversed curve is 500 m. If the angle of convergence between the second and the third tangents is 16°, I, = 47°. R1 =200 meters, I2 = 65°, R3 =160 m, and stationing at PC is 5+600. Hint: sine law. determine the stationing at PT at the end of the long chord. Answer for part A should be in this Format: x+xx.xXxx (FOUR DECIMAL PLACES i.e. 0+123.4567) determine the angle between the long chord of the compound curve and the first tangent. Answer in four decimal places (i.e. 12.3456)
