TM 5-5420-278-10 0035 00 0035 00-17 BRIDGE ANCHORAGE (Contd) EXAMPLE Given the following reconnaissance data, design the cable for an overhead cable system for the IRB: River width: 600 ft (183 m) Current velocity: 7 feet/sec (2.1 meters/sec) Available cable: 1/2-, 1-, and 1 1/4-in. (12.7-, 25.4-, and 31.8-mm) IPS cables SOLUTION Number/size cable: refer to table 5. A single 1-in. (2.5-cm) cable is sufficient for this system: Number of clips: (3 x CD) + 1 = 3 (1) + 1 = 4 clips at each end Spacing of clips: (6 x CD) = 6 in. (15.2 cm) apart L = (1.1 x 600) + 100 = 760 ft (215.3 m) CL = 760 + 250 = 1010 ft (308 m) S = 760 x .02 = 15.2 ft (4.6 m) Figure 12. Initial Sag.
