Determine the horizontal length of CD that must be laid out to achieve required true horizontal distance CD.
assume a 100-ft steel tape will be used, with crosssectional area 0.0060 in2, weight 2.0 lb, and standardized
at 68 0F to be 100.014 ft between end marks when
supported through out with a 12-lb pull.
