Q2) To measure a base line, a steel tape 30 m long standardized at 15°C with a pull of 100 N was used. If the temperature at the time of measurement was 20°C and the pull exerted was 160 N. 1- Find the correction per tape length. 2- If the length of 250 m is measured on a slope of 14", find the horizontal length. (Take E = 2.1x 10' N/mm', a = 11.2x10* C and cross-scctional area of tape = 0.08 cm?)
