Thanks Bob for finding those so quickly, but my question is more towards the engineering side of the design (which I am not) of the cable properties. Where would we input the cable weight, circular area, stretchability, etc. into that equation?

Down towards the bottom is a lisp routine that lets you input weight and tension. Unless they are lying or I are missing something.
