A 100-ft steel tape standardized at 68°F and supported throughout under a tension of 20 lb. was found to be 100.02 ft long. The tape had a cross-sectional area of 0.0078 and a weight of 0.03 lb/ft. This tape is used to lay off a horizontal distance CD of exactly 180.0 ft. The ground is on a smooth 4% grade; thus, the tape will be used fully supported. Determine the correct slope distance to layoff if a pull of 22 lb is used and the temperature is 67 °F.
