Set
1. What is the combined effect of curvature and refraction for a 300 foot long level shot?
2. A level loop closed -0.09'. There were ten turning points in the loop.
How much (and in what way) should the preliminary elevation of the seventh turning point be adjusted (± 0.01')?
3. An equal tangent vertical parabolic curve has the following characteristics:
PC Station is 23+28.97. PC elevation is 244.88'. L = 5.00 stations, G1 = +4.00% and G2 = -5.70%. Prepare complete stakeout notes (at full stations) for this data. Follow the same format as the example problem in the course notes.
