A 50 m steel tape was standardized and supported throughout its whole length and found to be 0.00205 m longer at an observed temperature of 31.8°C and a pull of 10 kg. This tape was used to measure a line which was found to be 662.702 m at an average temperature of 24.6°C using the same pull. Use coefficient of expansion of 11.6 x 106/0C. 3. Compute the standard temperature. 4. Compute the total temperature correction. 5. Compute the correct length of the line.
