A steel tape is 30 m long at a temperature of 15°C and a pull of 50 N when laid on a flat surface. The tape weighs 18 N. It is stretched between end supports only allowing it to sag. Find the correct length of the tape at a field temperature of 25°C at a pull of 115 N. If in the above condition a base line is measured and the recorded length of the line is 600 m, find the correct length of the base line. Take a = 12 x 10-6 per °C and E= 2 x 105 N/mm². Sectional area of the tape = 7.50 mm².
