A 30-m steel tape standardized at 20°C and supported throughout under a tension of 9 kg was found to be 30.005 m long. The tape had a cross-sectional area of 0.05 cm?, a weight of 0.04 kg/m, and its coefficient of linear expansion is 0.0000116/1 °C. This tape is used to lay off a horizontal distance CD of exactly 53.43m. The ground is on a smooth 3% grade; thus, the tape will be used fully supported. Determine the correct slope distance to layoff if a pull of 6.8 kg is used and the temperature is 30°C. Use E =2.10 x 10° kg/cm?.
