Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.

Jisoo used a 40 meter steel tape in measuring an inclined distance on a gentle slope. The sloping distance was recorded to be 440 meters long. The difference in elevation between the initial point and the end point was found to be 32.49 m. The 40-meter tape is of standard length at a temperature of 20 °C and a pull of 34 N. During measurement, the temperature reading was 44 °C and the tape was supported throughout its length with an applied pull of 82 N. The cross-sectional area of the tape is 1.54 mm^2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.68 kg. Determine the corrected horizontal distance in meters.
