A 100-ft steel tape was used in the field to measure a distance of 247.53 ft. the following data represents the conditions in the field at the time of measurement: tempreture = 41 F, tension = 30 ib, and tape supported at ends only. the tape used in the field had a cross-sectional area of .009 in^2 and a weight of 2.5 ib. the tape was standrized at 68 F with a pull of 20 ib when supported throughout and was found to have a length of 99.983 ft. Determine the true horizontal legth of the distance measured in the field.
