MODULE – 1
9. a) What is ranging ? discuss the various methods of ranging. 8
b) To measure a base line, a steel tape 30 m long standardised at 15°C with a pull
of 100 N was used. obtain the correction per tape length if the temperature at
the time of measurement was 20°C and the pull exerted was 160 N.
E = 2.1×107 N/cm2, a = 7.1×10–7/°C, wt of 1cm3 of steel = 7.86 gm. 12
