Derive an expression for correction to be made for effect of sag and slope in base line measurement introducing the case where the tape or wire is supported at equidistant points between measuring pegs or tripod |
|
Answer» tion:In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction DUE to temperature, and the tape's sag, which varies with the APPLIED tension. Not correcting for these EFFECTS gives rise to systematic errors, i.e. effects which ACT in a predictable manner and therefore can be corrected by mathematical methods.Please MARK me as brainliest!! |
