The difference in elevation between line AB is 6.5m. A 100 meter steel tape was used with a standard pull of 12kg under a temp. of 30degC. The line was measured on a sloping ground and found to be 486.396m. But during the measurement, the temp. was 18degC and the tape was suspended under a pull of 18kg. The tape weighs 0.75kg and it was supported at 0-30-75-100 marks when measuring. Determine the correct slope distance and horizontal distance. A = 0.04 sq. cm.
can you pls help me understand how this is solve.. so that I can do it on my own.
