SITUATION VI. A vertical symmetrical sag curve has a descending grade -5.2% and an ascending grade of +3.25% intersecting at station 12 + 040, whose elevation is 130m. The two grade lines are connected by a 290m vertical curve. 12. At what distance from PC is the lowest point of the curve located? a. 178.46m b. 180.41m c. 160.22m d. 175.71m 13. What is the vertical offset of the parabolic curve to the point intersection of the tangent grades? a. 3.425m b. 3.021m c. 3.063m d. 3.122m
