More things broken

The winter before Dr Pete Donzelli was killed I met him and some other arbos i Colorado for a week of skiing. Pete and I paired up because we both telemarked and skied about the same. He was better and shared so many tiny details about body form with me. By the end of the week
I was almost able to keep up with him when we're tree skied

We talked about soooo much on the lift rides. Pete is the one who brought science to rigging. Recording load cells hadn't been used before. His research was the beginning of our professions understanding about loads and friction. One limit that pete acknowledged was that we could only measure loads at an attachment point. At that time load cells weren't the cigarette package size units we have today. What he really wanted was a way of capturing loads all along the rope and from surface to core cross section. Translate our view of a load from a point in time and space to one where we would see loads spread through or ropes, gear and the tree itself. Engineers in material science are able to do that using compuger modeling as well as in real life scenarios. At some time we'll be able to see a load a sheet that covers and penetrates our systems not just the point that we're familiar with now

I miss ya, Pete!

... One could almost say... there's too many variables involved in tying knots with enough consistency for them to be considered safe. Oh, wait... I must be thinking of hand sewn splices.

Haha! Touche. But there are so many things that knots can do well, their limits are well-documented, they are easy to inspect and fun to tie. They are part of the rope and they will respond within the rope's characteristics, not apart from it like the thread used in the hand-sewing of an eye.
 
How bout some cycles to failure testing.. Could adapt a home made machine like this power hammer to tug on a rope 10,000's of times a day, It would be pretty simple to calculate..
