Question

PROBLEM 8. The following data has been taken and calculated for a 5-course loop traverse. CourseLength Latitude AB rture 1005 24 +335.34 395.75 +244.83 +436.84 870.53+775.38 1034.62 550.71 CD DE EA 1178.72 364 27 112102 1094.06 1092.65 -55.49 The coordinates of A are x 2000.00; y 1500.00. Sketch course AB. Correct the latitudes and departures of courses AB and BC with the compass rule and report the coordinates of station B. (15 points) PROBLEM 9. The following data has been already calculated for a horizontal curve: Point of Intersection 35+80.00 Tangent Length 367.55 ft Radius 636.62 ft Total Deflection Angle 60 degrees Degree of Curvature 9 degrees Sketch the curve, showing all of the above information. Assuming an instrument is set up at the point of curvature, calculate the cord and deflection angle for staking the first full engineering station on the curve. (10 points) PROBLEM 10. A road segment has a base width of 50 feet and is being built in a fill section. The slope stake notes for STA 35 and STA 36 look like: L C R 36 F8.3 F8.3 F8.3 35 F6.4 F64 F6.4 Sketch the cross-sections. Using the end area formula, compute the volume ofill between 49.9 0.0 49.9 442 0.0 44.2 these two stations. (10 points)
