A 800-ft equal-tangent sag vertical curve connects tangents that intersect at elevation 650 ft. The curve starts at station 20+30. The initial grade is -3.5% and the final grade is +2%. Determine the elevation of the middle point of the curve.
A 750-ft equal-tangent crest vertical curve connects tangents that intersect at elevation 572 ft. The curve starts at station 15+25. The initial grade is +5% and the final grade is -3%. Determine the elevation of the middle point of the curve.
An equal-tangent sag vertical curve is designed for 45 mi/h. The low point is 237 ft from the PVC at station 112 + 37 and the final offset at the PVT is 19.355 ft. If the PVC is at station 110 + 00, what is the elevation difference between the PVT and a point on the curve at station 111 + 00?
