Elastic modulus of wire rope
Elastic modulus of wire rope
(OP)
This question is automotive-related only because I'm working on a trailer that will haul a race car.
I don't have an M.E. degree and I couldn't find the answer in Machinery's Handbook.
I need a ballpark value of modulus of elasticity (in tension, of course!) of a cable of 1/2" diameter, 6 x 19, galvanized finish. Assume the material is a "good" steel alloy with a nominal modulus of 30 x 10^6 PSI.
Thanks.

I presume the 6 19 is number of yarns and number of strands per yarn.
I can't answer your question, but I would think whoever does, needs the twist data.

There ought not be any self-created structure that's being loaded under use. That's just asking for lawsuits if it ever breaks.

My book shows:
3/8' 6 x 19 FC IPS has a breaking strength of 12,200 lbs and a safe load of about 1952 lbs. using a 5:1 Safety factor. Don't ask why it is not 12,200/5 = 2440 lbs. cause I don't know!
