A 30-m steel tape standardized at 20°C and supported throughout under a tension of 5.45 kg was found to be 30.012-m long. The tape had a cross-sectional area of 0.050 cm2 and a weight of 0.03967 kg/m. Ts tape was held horizontal, supported at the ends only, with a constant tension of 9.09 kg, to measure a line from A to B in three segments.The modulus of elasticity E = 2.10 x 10^6, and the data listed in the following table were recorded. Apply corrections for tape length, temperature, pull, and sag to determine the correct length of the line. Transcribed Image Text: Measured (Recorded)
