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.
REQUIRED AVERAGE MEANS OF TENSION
HORIZONTAL TEMPRATURE SUPPORT (lb)
DISTANCE CD (ft) (0F)
200.00 68 Throughout 12
378.68 37 Ends only 16
97.00 46 Ends only 18
