A distance was measured on a uniform slope of 7% and was found to be 2345.21 ft. The tape temperature at the time of the measurement was 18 degree F, the tension was 10 Ib and the tape was supported throughout ts full length. What is the correct horizontal distance measured if the tape is 100.05 ft long at 58 degree F and Ib tension, when supported throughout its full length? The tape cross-sectional area is 0.015 in2, the coefficient of thermal expansion expansion is 6.5 times 10-6/degree F, and the modulus of elasticity 2.9 times 1.03 lb/in~2.

Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.
