elevation 854.00 ft at station 20 + 50. Field conditions require a highway curve to pass through a fixed point. Compute a suitable equal-tangent vertical curve and full-station elevations. Give the elevations in order of increasing X . Express your answers in feet to five significant figures separated by commas.

I have tried and end up with the wrong answers. Please help.

2. Compute by hand and tabulate station elevations and the 1st and 2nd differences for an equal tangent parabolic (vertical) curve for the following data: A +3.50% (g1) grade meets a -4.00% (g2) grade at Station 12+65 (the PVI). The PVI Elevation = 300.00'. Length of Curve = 750'. Calculated elevations for full stations between the BVC and the EVC. Also, calculate the station and elevation of the curve for the PVI, BVC, EVC and the High Point. Place all the information in station order in a properly labeled and organized table using the exact format shown in the last slide of the Application of Vertical Curves Video. Show all elevations to 3 decimal places. Provide a page sized detailed and labeled sketch of the profile of the curve. Deliverables: Your calculations, sketches and tables should be submitted by the syllabus deadline as a properly named single PDF document. The order for the information in the submission PDF is to be as follows: Problem 1 Hand Calculations Problem 1…

Tabulate station elevations for an equal-tangent parabolic curve for the data given in Problems 25.4 Othrough 25.9, and check the table by second differences. 25.4 A-2.50% grade meets a +1.75% grade at station 44+25 and elevation 3386.96 ft, 400-ft curve, stakeout at half stations.
