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 12.5kg. The slope of the measured line is 2-degree 40minutes. The tape weighs 1kg, standard pull of 8.5kg, cross-sectional area of 0.039cm^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?
