A 100 ft steel tape of cross-sectional area 0.0025 in2, weight 2.0 lb, and standardized at 68°F is 99.983 feet between end marks when supported throughout under a 10-lb pull.

a. What is the true horizontal length of a recorded distance AB if AB was measured to be 140.23 ft? At the time of measurement, the average temperature was 55°F, the tape was unsupported and there was 17 lbs of tension on the tape. (Assume horizontal taping and all full tape lengths except the last.)

You are measuring a line with a steel tape that has a standardized length equal to 100.000 feet and a weight of 2.25 lb. Three full tape lengths and one partial length were used when making the measurement, resulting in a recorded length of 389.28 ft. The tape was supported at ends only and a pull of 12 pounds was used. What is the distance after being corrected for sag? CORRECT ANSWER IS 389.82ft
