It doesn't seem to be an issue of you not getting it, but not even trying to. For that, clarifying my points will do nothing, so I'll leave it alone. Cheers, GO I think Sty is right. Nope. Even if he was correct that the peak force from sitting back on a dynamic line is not higher than the weight of the climber, he is still wrong about his calculation on the force the top piece feels. It would not feel 2X the weight of the climber, but ~ 1.6X. Do you know why?
In reply to: I would like a link to rgold's post that you referred to or a better explanation. You are just giving the jt512 validation right now. I will provide a link shortly (as soon as I track it down!) Meanwhile, if you don't actually care about the math, you can just confirm his results by going to the Petzl fall simulator. Put in a fall factor zero, and you will see it reports the force on the top piece at ~ 3.4 times the weight of the climber. GO
