Question
A 50-m steel tape is of standard length under a pull of 5.50 kg and a temperature of 20°C when supported throughout its entire length. The tape weighing 0.05 kg/m, has a cross sectional area of 0.04cm2 and a modulus of elasticity of 2x106 kg/cm2. This tape was used in the field to measure a distance that was determined to be 458.65m. At the time the measurement was made, a constant pull of 8kg was applied with the tape supported at endpoints only. During the measurement, it was a cool atmosphere at an average temperature of 18°C. Determine the correct length of the line.
