A steel tape of nominal length 30m was suspended between supports to measure the length of a line. The measured length of the line on slope of angle 30 50’ is 29.859m. The mean temperature during the measurement was 120c and the pull applied was 100N. If standard length of the tape is 30.005m at 200c and the standard pull is 45N, calculate the corrected horizontal length. Take:-  w= 0.15N/m  A= 2.5mm2 ᾱ= =1.15*10-5 /0c  E=2.0*105N/mm2
