to measure a base line, a steel tape 30m long standardised at 15 degree Celsius with a pull of 100N was used. Find the correction per tape length, if the temperature at the time of measurement was 20 degree Celsius and the pull exerted was 160N weight of 1cm3 of steel is 0.0786N and weight of the tape=8N, E=210000kg/m2, coefficient of expansion of tape per 1 degree celsius is 0.00000071.
