A steel surveyor's tape is to be used to measure the length of a line. The tape has a rectangular cross section of 0.05 in. by 0.2 in. and a length of 100 ft when T1=60?F and the tension or pull on the tape is 21 lb . Determine the true length of the line if the tape shows the reading to be 463.22 ft when used with a pull of 38 lb at T2=90?F. The ground on which it is placed is flat. ?st=9.60(10^?6)/?F, Est=29(10^3)ksi.

PROBLEM 1. A 310.00 ft. line is to be staked-out with a steel tape (fully supported along the flat floor) inside a large warehouse. The tape is to be pulled at 30 lb. The tape is known to be 99.990 feet long when pulled at 10 lb at 68 degrees F, fully tape is 0.0030 sq. in. The elastic modulus is 29,000,000 psi. The temperature inside the warehouse is 68 degrees. What distance on the tape must be used to...

An example of a systematic error is the effect of temperature on a steel tape. 2. Slope, tension, sag and temperature corrections made to field measurements is a form of random errors, T F3. Estimation of air temperature or horizontal position of tape/chain are considered systematic errors. TF4.Examples of mistakes are transposing figures or miscounting the number of full tape lengths in a long measurement. The effect curvature and refraction has on a measurement is considered a random error. T...
