. A 40m steel tape is suspended in the air between a theodolite and vertical rod, which is placed exactly at the 40m mark, under a pull of 12.6kg. The slope of the measured line is 2- degree 55-minutes. The tape weighs 1kg, standard pull of 8.2kg, cross-sectional area of 0.042cm^2 and E= 2x10^6 kg/cm^2. a. Determine the correction for sag of the tape in meter. b. Determine the horizontal distance between the theodolite and rod in meters. (Apply 5- decimal places, for letter B only) c. What additional pull must be applied to eliminate the effect of sag?
