A grade line AB having a slope of -4% intersect another grade line BC having a slope of +2% at B. The elevations of points A, B and C are 93 m, 87 m and 92 m respectively. Determine the:
a) elevation of the sag of the 200 m vertical parabolic curve to connect the grade lines;
b) location of sag from where the curve starts;
c) station of sag if PI is at station 10+20 (format: 00+00.00);
d) vertical distance from point B to curve;
e) elevation at station 09+80.
Grade Diagram is drawn to find elevation between stations.
All parameters and their equations are shown.
