'ere be a 200 year ole family secret for 'how strong'...When you need a steel cable, for a shroud, stay, etc. and you know your load but not wot size cable to use, you take the number of eighth's in the diameter of the wire, squared...(!/2"=4 eighths, so 4x4=16) divide the answer by 8, and the answer you have is the strength of the cable in tons,choked or made into an eye about itself..So, 1/2 inch cable is 4x4=16, divided by 8=2 tons breaking strength with a safety factor of 5.....
