Survey Exam‏

Name: _ Student Number: _ Exam #3 (Saturday 5/2/2015) Provide All calculations on Engineering paper to be stapled to this exam. Any calculation/ answer written on this exam (except the provided tables) will not be considered. Name: _ Student Number: _ Part I) Area Calculation: a) Determine the area of the parcel that the 5 points create. Use straight lines between AB, CD, DE, EA, and an inward curve between points B & C. b) What is the bearing of line CD? c) What is the distance of line AE? (Hint: a sketch will help) A = N: 8,451,000.0000 E: 8,451,000.0000 B = N: 8,451,111.9100 E: 8,451,005.0600 C = N: 8,451,159.8700 E: 8,451,066.0300 D = N: 8,451,139.9500 E: 8,451,137.3400 E = N: 8,450,999.9750 E: 8,451,134.9200 Curve Data Between B & C Chord length = 77.5726’ Radius = 45.00’ Δ = 119˚ 03’ 54” Name: _ Student Number: _ Part II) Vertical Curves: A vertical curve has a back tangent entering at +2.75% and exiting at -1.25%. The station of the PVI is 8+25, has an elevation of 245.75, and a length of 400.00’. Determine the following: 1. Provide The Following (On the chart provided) a. Stations & Elevations of the low point or high points (LP/HP) b. Complete all the information for the PVC, PVT, and curve elevations at every half and whole station. Sta. x y Elevation on Tangent line Elevation on Curve Name: _ Student Number: _ Part III) Volume Calculation: Using the table provided, calculate the total volume of material (cut or fill) required between stations 24+00 and 28+00. Use the average-end-area method. Station Area (ft2 ) 24+00 135 25+00 343 26+00 64 26+85 0 27+00 -169 28+00 -294 Name: _ Student Number: _ Part IV) Tape Corrections: A steel tape was calibrated at a temperature of 68˚F and 12 pounds of tension while fully supported. The tape has been found to have a length of 100.02 feet between the 0.00 foot and 100.00 foot marks. The cross-sectional area of the tape is 0.005 square inches. The modulus of elasticity of steel is 29,000,000 pounds/ square inch. The total weight of the tape is 2.50 pounds. This tape has been used to measure a distance AB in the field. The recorded distance is 7,485.49 feet. The field notes read that the temperature during the first 5,000.00’ was 97˚F. The reminding measurement was made at 81˚F. It was also noted that the measurement was taken along a -2.25% slope while being fully (continuously) supported. 12 pounds of tension was applied to the tape during the entire measurement. What is the corrected horizontal distance from point A to B? Name: _ Student Number: _ Part V) Volume Calculation: Using the figure and table provided, calculate the amount of material excavated (in cubic yards). Location Change in Elevation A 10.45 B 5.48 C 9.86 D 9.85 E 7.48 F 6.99 G 4.26 H 15.99 J 18.95 K 9.48 L 17.48 M 16.98 N 5.99 Name: _ Student Number: _ Part VI) The bearings for the triangular parcel of land are as follows: Line AB = N 13 deg 27’ 56” E Line BC = S 21 deg 18’ 28” E Line CA = S 40 deg 36’ 08” W See sketch below, not to scale What are the interior angles for all 3 angles in the triangle?
