Geomatics 3. Field conditions require a highway curve to pass through a fixed point with elevation 753.00 at station 30+00. Compute a suitable equal tangent vertical curve and full-station elevations if g!--2.50%, g2 +1.00%, VPI elevation- 750.00 ft, VPI station 30+00. Include a hand sketch of the curve.
2. A 600-foot, equal tangent vertical curve has grades g = -1.2% and g = +3.40%, a VPI at station 135+60.00. The elevation of the VPI is 833.69 feet. Tabulate elevations for the VPC, VIT, and each station; check by second differences.
There should be seven different elevations for the answer Problem 25.8 3 of 5 > A 530-ft curve, g,--1.00%, g,-+4.90%, VPI stations 46+00, VPI elevation 1350.00 ft, stakeout at full stations. Part A Tabulate station elevations for an equal-tangent parabolic curve for the data given above.

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...
