A control cable is being pulled into 30 ft of 3′′ trade size conduit. See figure below for physical layout. We have a choice for the direction of the cable pull as shown by part (A) or part (B) of the figure below. SWBP of cable is 500 lbf/ft and coefficient of friction is not known but assumed to be no greater than 0.5. For this problem, use Table 14.14 for cable data. For both the cable pull direction shown in part (A) and the cable pull direction shown in part (B), determine the following.
(a). The total effective conduit length
(b). The total degrees of bend
(c). The maximum allowable effective conduit length for cable specified
(d). The maximum pulling tension for application
(e). Is this cable pull allowable from the direction indicated?
