Q2)In a vertical curve, the grade of tangents are -2.5% and 5% respectively, and rate of change of the grade of curve is 0.5% per station. The elevation of P.V.T is 20 m, and location (18+18.18). Determine 1- the elevation and location of changing point on the curve. 2- the vertical distance from P.V.l to the curve. 3- Elevations and locations of main stations.

The elevation of P.V.T is 20 m, and location (18+18.18). Determine 1- the elevation and location of changing point on the curve. 2- the vertical distance from P.v.I to the curve. 3- Elevations and locations of main stations.
