Wire Rope D/d efficiency
Wire Rope D/d efficiency
(OP)
Greetings everyone! This is my first post to this site, as I've come across it in trying to find the D/d efficiency equations. I look forward to helping the best I can, and I hope to get as much back from this site. Unfortunately, I'm a man without a home here. I'm a rigging engineer, with structural steel background. I'm a little disappointed that there's not a thread for that, but I'll adapt. Meanwhile, if anyone has Crane & Rigging questions, I'll help the best that I know how.
Here goes: I've recently switched jobs, and somewhere during the move, I've misplaced all of my "cheat sheets" that had my most frequent equations, formulae, etc. on them
I CAN'T FIND THE (2) EFFICIENCY EQUATIONS OF WIRE ROPE W.R.T. THE D/d RATIO! Can someone please help?

RE: Wire Rope D/d efficiency
FYI:
When D/d < 6:
%E = 1 - (1/(2*(SQRT (D/d))))
When D/d >= 6:
%E = 1 - [.76 / ((D/d)^.73)]
