The distance recorded for a
baseline was 430.60 using a 100 m steel tape
standardized at 15C and with a standard
pull of 10 kg. At the time the temperature
was measured to be 20C and the pull
exerted was 16 kg. Unit weight of steel is 7.86
g/cc and weight of steel is 2.67 kg, E =
200000 MPa,  = 70 x 10-6 m/C.
