a 50-m steel tape is of standard length under a pull of 5.5 kg when supported throughout its length. the tape weighs 0.05 kg/m, has a cross-sectional area of 0.04 sq. cm , and being made of steel , its modulus of elasticity is 2.10 x10^6 kg/cm^2. this tape was used in the field to measure a distance that was determined to be 458.650 m. at the time the measurement was made, the constant pull applied was 8 kg with the tape supported only at its endpoints. determine the following: a) Correction measure line due to tension b) Total correction due to sag c) correct length of measured line corrected for effects of tension and sag
