The forward and the backward tangents of a simple curve have an azimuth of 249°15' and 190°45' respectively. The distance from the middle of the chord to the vertex is 57.73 m. And the stationing of the vertex is 2+501.21. a) Determine the radius of the curve. b) Determine the stationing of P.C. c) Determine the stationing of P.T.

The azimuths of the back and forward tangent of a spiral curve are 220° and 290° respectively. If the length of the spiral is 80m and the degree of the circular curve is 4°, determine: a. The distance between the vertex and the middle of the curve. b. The short tangent at the SC point. c. The long tangent at the SC point. d. The station of CS if the station of TS is at (7+028).
