A 30m steel tape standardized at 20-degree Celsius and supported throughout under a tension of 5.65kg was found to be 30.018m long. The tape had a cross-sectional area of 0.055cm^2 and a weight of 0.03697kg/m. This tape was held horizontal, supported at the ends only, with a constant tension of 9.98kg, to measure a line from A to B in three segments. The data listed in the following table were recorded. Apply corrections for tape length, temperature, pull and sag. Determine the correct length of the line. Use E= 2,000,000kg/cm^2. Apply 4-decimal places.
