A steel tape of nominal length 30m was used to measure a line AB by suspending it between supports. The following measurements were recorded Line Length measured slope angle mean temperature tension applied AB 3°40 29.872 5° 120N The standardized length of the tape against a reference tape was known to be 30.14m at 20 and 50N. If the tape weighs and has a cross sectional area of 2mm, calculate the horizontal length of AB. Young's modulus (E) for the tape is 200 and the coefficient of thermal expansion (a) is 0.0000112 per °C

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.
