Wire rope length change as it twists
Wire rope length change as it twists
(OP)
I'm looking for an equation or chart that could tell me how much a wire rope shortens if you twist it. I'm not talking about the length change of the strands during manufacture of the rope. If you take a finished rope and twist it further, how much will it shorten per turn? I've looked through several reference books without success.

Aircraft cable is pre-stretched, and we calibrate our length while the full operational load is applied, so I think that should take care of constructional stretch. A steel belt might have been a good idea, but this is an existing construction I have to deal with.
