Situation no. 2 The line AB was measured by a 50-m steel tape and found to be 680 meters at temperature 28°C, pull at 4.50 kilograms while supported at two ends. The tape was known to be 0.002 meter too long at temperature 30°C, pull of 2.25 kilograms while fully supported. The tape weighs 0.80 kg and the unit weight of steel is 7,860 kg/cu.m and the modulus of elasticity is 2.1136 x 106 kilogram per square centimeter. 4. Determine the correction due to variations in pull in mm. 5. Determine the correction due to sag in mm. 6. Determine the correct length of line AB in m.
