I was simply saying that the reduction in friction was part of "spreading" the load. I suppose that in the real world, that is not a true definition. That said, I will withdraw to an observation-only stance and commence banging my head against the wall.:banghead:

True, Burnham, but pulling oneself up in a DRT system is much easier with a friction saver versus a natural crotch, which is why I mentioned the reduced friction as a factor. (I thought it was clear that the pulleys allowed more legs of rope to come into play.) No, the elimination of friction is...

Jed, think about natural-crotching a 100# limb down. If the limb hangs and must be lifted by the groundie, it's quite difficult, due to friction at the crotch. If the same limb were lowered with a block or pulley, the reduced friction would allow him to lift the limb with much less effort. Same...

When you run the rope back through a loop, you create a z-rig, or 3:1, simply without pulleys. What the pulleys do is reduce friction to near (or almost) nothing. This saves wear on the rope as opposed to running it through a loop, as well as yields more pull for your effort. It's true that you...

The reason the 3 + 3 = 9 is because the first 3:1 system is piggy-backed onto the second 3:1 system. If two 3-sheave pulleys were used, it would yield 6:1. How many folks on here use fiddle block/block-and-tackle systems very often? I have a couple of double-sheave pulleys that I can set up for...
