a Question 2 [45] A grade gı of -4.00% intersects grade g2 of +2.00% at a vertex whose station and elevation are 6+ 920.000 and 625.00 m, respectively. An equal-tangent parabolic curve 240 m long has been selected to join the two tangents. You are required to a) Draw a sketch for the vertical curve that shows BVC, EVC, V, 91, 92, and L [5 points], b) Calculate the BVC station and elevation [5 points), c) Calculate the EVC station and elevation [5 points), d) Compute and tabulate the curve elevation for staking at 90 m increments [ 20 points), and e) Calculate the position and the elevation of the lowest point ( 10 points).
