In a certain road construction undertaken by the Bureau of Public Highway it was decided to connect a forward tangent of 3% and a back tangent of - 5% by a 200 m. symmetrical parabolic curve. It was discovered that the grade intersection at station 10+ 100 whose elevation is 100 m, falls on a rocky section with an outcrop of 2.67 m. directly above the grade intersection. To avoid rock excavation, the project engineer decided to adjust the vertical parabolic curve in such a way that the curve will just clear the rock without altering the position of P.C. and the grade of the tangents. (a) Determine the total
