Line AB was determined to be 2395.25m when measured with a 30m‐steel tape supported throughout its length under a pull of 4kg and at a mean temperature of 35°C. The cross‐sectional area of the tape is 0.03 cm^2, coefficient of thermal expansion is 0.0000116/°C and modulus of elasticity of steel is 2.0x10^6 kg/cm^2. Determine
a. Correction for the measured length due to temperature if the tape used
is of standard length at a temperature of 20°C. Is the tape too long or too
short?
b. Correction for the measured length due to tension if the tape used is
of standard length at a pull of 5 kg. Is the tape too long or too short?
c. Correction for the measured length due to sag if it weighs 0.04kg/m
d. the corrected length of line AB considering corrections from (a), (b) and (c)
