50-m steel tape is of standard length under a pull of 55 N and a temperature of 20°C when supported throughout its entire length. The tape weighs 0.055kg/m, has a cross sectional area of 0.04 cm² 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 501.650 m. At the time the measurement was made, the constant pull applied was 80 N with the tape supported only at endpoints. During the measurement the temperature was observed to be at an average of 18°C. Use a = 11.6x10-6 m/"C a. Determine the correction due to tension. b. Determine the correction due to change in temperature. C. Determine the correction due to sag. d. Determine the correct length of the line.
