1. A steel tape, known to be of standard length at 25°C, is used in laying out a runway 1.5 km. long. Determine the temperature correction and the correct length to be laid out when the temperature is 38°C. 2. A 50 m. steel tape is of standard length under a pull of 5.5 kg. when supported throughout its length. The tape weighs 0.05 kg/m, has a cross sectional area of 0.04 sq. cm. This tape was used in the field to measure a distance that was determined to be 488.65 m. At the time of measurement, the constant pull applied was 8 kg. with the tape supported only at its endpoints. Determine the correct length of the line. 3. A 50 m tape was standardized and found to be 0.0015 m longer at an observed temperature of 31.5°C under a pull of 10 kg. The same tape is used to measure a line found to be 523.61 m at an average temperature of 24.5 °C using a pull 12 kg. What is the correct length of the line?
