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 120 c and the pull applied was 100N. If standard length of the tape is 30.005m at 200 c and the standard pull is 45N, calculate the corrected horizontal length. Take:- w= 0.15N/m A= 2.5mm2 ᾱ= =1.15*10-5 /0 c E=2.0*105 N/mm2

Question
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 120
c and the pull applied was 100N. If standard length of the tape is 30.005m at
200
c and the standard pull is 45N, calculate the corrected horizontal length. Take:-
w= 0.15N/m
A= 2.5mm2
ᾱ= =1.15*10-5 /0
c
E=2.0*105
