3. The offset distance of the simple curve from the P.T. to the tangent line passing through the P.C. is equal to 100m. The simple curve has an angle of intersection of 50°. A. Evaluate the length of the long chord. B. Evaluate the tangent distance. C. If the stationing of P.I. is 7+421, solve for 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).

The slope dv/dx is positive when the tangent to the elastic curve slopes upward to the right. O False True L MO B UN
