Please help me ASAP. Please put the answer on the paper. Complete solution. I need the answer after 40 minutes. Rate will be given accordingly. Thank you in advance.Line AB was measured and the result is 745m. It is measured using a 30m tape that is0.005m tooshort. The tape is standardized at 20°C under a 4.5kg pull. During measurement the temperature is30°C under a pull of 9.57kg. What is the true horizontal distance of line AB due to incorrect tape length,temperature, and pull? The cross-sectional area of the tape is 0.05cm2 and E = 2x106 kg/cm2.

2. Determine the standard temperature of the steel tape and the length of the line measured, if it was found out that at 35°C the total error due to temperature occurring was 0.03m while at 45°C the total error due to temperature occurring was 0.10m. Use C= 0.0000116/1°C.
A line was found out to be 2865.35 m long when measured with a 30-m tape under a steady pull of 6.5 kg at a mean temperature of 30 degC. Determine the correct length of the line if the tape used is of standard length at 20 degC under a pull of 5.5 kg. Assume that the cross-sectional area of the tape is 0.025 cm², elastic modulus of tape is 2.10 x 106 kg/cm? and coefficient of linear expansion of steel is 11.6 x 106 per degC.
