So It seems I am way over my head here, mathematically. I had never heard of a quartic function and can't make sense of the answers I get when I run my numbers on a quartic function calculator I found online. I guess I was expecting a single answer. I feel like there has to be a simpler...
The first thing I'm running up against is the l0 vs. lp. How are those two values substantially different? If I pull a line from point to point that should be the pretension length regardless of the amount of tension I apply. If l0 is the slack length then how does that affect the parts...
Thanks,
It'll take me longer to vet these calcs than it took you to conceive them... Will check back in if they seem right.
BTW does anyone have a reliable source for the K value of wire rope? The best I could find was http://www.latchandbatchelor.co.uk/rope-info/rope-data/" .
I get the question... There are several real-world solutions that would work, [even in California] but I think the OP wants a math exercise... I say that hanging it by two nails and a continuous string won't work so well in reality. I'm with an earlier poster who suggested cutting the string...
I have been asking this question of everyone I meet and can't find a straight answer.
Imagine a wire rope anchored at both ends, spanning 50ft [15m].
That line is 'pre-tensioned' to... say 500 lbs. [2kN].
The idea is that it is pulled fairly 'flat'.
What happens to the line tension when I...
