Q: The lengths of the sides of a plot of land were measured, and they were equal to (200 x 300 m) using a bar of nominal length (30 m) and real length (29.995 m) at a temperature of (10) degrees Celsius. Calculate the magnitude of the tension applied during work, which gave the measured dimensions equal to the real dimensions if the tape was suspended from both ends when measuring the long side and resting on the ground when measuring the short side. Note that Ts = 200 C, Ps = 45 N, a = 0.0000115/ C° ,and 9 A = 2 mm2 , W = 0.8 kg E = 200 kN / mm2 E =

A 50 m tape weighing 0.049 kg/m with a cross-sectional area of 0.05 sq. cm and modulus of elasticity equal to 2x106 kg/cm2 is used in determining the distances between two points. The tape is of standard length under a pull of 6.70 kg and a temperature of 25°C when supported throughout its entire length. The tape was then used in the field to measure a distance that was determined to be 378.123 m. At the time the measurement was made, the constant pull applied was 9 kg with the tape supported only at endpoints. During the measurement the recorded temperature was 17°C. Use o=11.6x10-6/C. Determine the correct length (in feet)of the line. Youranswer
A 30-m tape of 0.05 kg/m weight was used to measure a distance. The measured length is 800 m. During measuring, the pull at ends of the tape is recorded to be 30 kg. Calculate the following: a. Error in measurement if the tape is used with its ends supported. b. Corrected length if the tape is used with its ends supported. c. Corrected length if the tape is supported at every 15 m.
