A 50m steel tape is used to measure the distance of the line and found to be 2153.3528m. During measurement, the tape is supported at the ends and every quarter point under a pull of 17 kg and the observed mean temperature is 29°C. The tape is of standard length at 23°C and a tension of 13 kg. The cross-sectional area of the tape is 0.037 cm?. The coefficient of thermal expansion is 0.0000116/°C and the modulus of elasticity of steel is 2.0x10 kg/cm. The tape weighs 1.1 kg. Determine the correct length of the tape.

Transcribed Image Text:A 50m steel tape is used to measure the distance of the line and found to be 2153.3528m.
During measurement, the tape is supported at the ends and every quarter point under a pull
of 17 kg and the observed mean temperature is 29°C. The tape is of standard length at 23°C
and a tension of 13 kg. The cross-sectional area of the tape is 0.037 cm?. The coefficient of
thermal expansion is 0.0000116/°C and the modulus of elasticity of steel is 2.0x10 kg/cm.
The tape weighs 1.1 kg. Determine the correct length of the tape.
