STEEL WIRE FOR CABLES.
Steel wire is now used in the manufacture of ships’ cables and tow ropes. The ropes and cables thus produced are remarkable for their strength and flexibility, and for the small space they occupy in comparison with hemp ropes and chain cables. A rope lin in diameter will bear a strain of 100 tons, without breaking the strength is uniform throughout; whereas, on testing chain cables, defective links are always discovered. The cost, too, is moderate. A ship of 3000 tons must have 360 fathoms of 2|in chain cable, which weighs 45 tons, costs about £I2OO, and is tested up to 91 tons of breaking strain. A steel cable 3Un in circumference, equal, as above stated, to more than 100 tons of strain, costs £4OO only, and weighs not more than five tons in the same length — namely, 360 fatho.ns.
