A 50m steel tape is used to measure the distance of the line and found to be 873.25m. During measurement, the tape is supported at the ends and midpoint under a pull of 8 kg and the observed mean temperature is 28°C. The tape is of standard length at 22°C and a tension of 12kg. The cross-sectional area of the tape is 0.033 cm?? The coefficient of thermal expansion is 0.0000116/°C and the modulus of elasticity of steel is 2.0x106 kg/cm?? The tape weighs 1.E kg. Determine the correct length of the tape.
