    Physics Question: Basal vs Canopy Anchor Forces

    Backwards is always good way to look at things, even if just as a parity check of what regular way looks like; but oft gifts different view too. Just like a tough maze, played backwards as a kid. . There are 2 dimensions of forces here: horiz/vert at play; depends on if and how you may...

    Downed pole with live wires

    i was shown for high power lines down, can lead with bare forearm and watch for hair movement. Not sure how much charge that takes, but seen it work.

    Physics Question: Basal vs Canopy Anchor Forces

    It is truly, truly a wonder, how can pareto/'pare to'(link) the same vital few pivotals, that blossom to so many outcomes that we chase on outer layer >>going instead to other end of the pivotals not outcomes >>can sometimes eliminate chase >>as it is all there>>pivotals with input/output arms...

    backwards walking

    Reverse thinking always good exercise, and sometimes solution or parity check of solution; but many times a fresh look in any case. >>even as tough maze forward when kid>>sometimes more sense backwierdz. Another counter of usual for expansion from East is doing Tree in yoga on 1 leg, then while...

    Physics Question: Basal vs Canopy Anchor Forces

    To me, the over the top lacing usability performs better: >>doesn't just test, but braces the top >>thus can flex top more sometimes with more confidence>>which is more input pull >>would seem to give more of a rolling input to a rolling output, especially to backlean >>easier untie after down...

    Bowline slippage

    DBY and a friction hitch are my test knots >>if rope does not lend and seat well, to hold well >>am probably not interested in it w/rare exceptions >>fishing like don't, has own class of knots >>prefer Bull Rope to pass test, but have carefully worked with them when don't >>stopper knot, but...

    Climbing a tall tree with shorter rope(s)…

    Wow, never did a climb like that, but basic too short of a line for me (in DdRT) was grab host can reach, and when get to it, make sure it could not drift up (or to sides) by natural architecture of tree or contrived with sling/carabiner set. As climb with lanyard, every body length or so put in...

    RADS/Yo-yo mechanical advantage

    Terms picked up hear (or at our previous bus stop on the tour at the late, great ISA forum, o sorry we said BBS back then...)from one mr. Tom Dunlap : closed vs open systems to view by(ty sir,1word/closed as a torch lit the way). The wonder of life in a curious state of DdRT(closed, recycling...

    Negative rigging with clevis

    Used a number of times, even away from trees. Cranes, towing etc. industrial grade link fer sure. Clevis is real 2 leg support to me, carabineer is more single leg like well 'moused' hook ( tinyurl.com/army-rig page.86 pic:3-4) fortifying solid leg ; but only 1 solid leg. Note tight bands in...

    Running bowline on anchor sling

    i think an upgrade from 1x arc180 (as in single Bowline) to 3x arc180 (of as a Double Bowline or Half-Hitch conversion to Anchor Hitch, to each side for Girth to Prussic etc.) is an upgrade to as a pro-level performance from basic level (except where curiously noted for Blackwall/hook as 2nd in...

    Running bowline on anchor sling

    Running Bowline, Timber would look at as 'single bearing', right angle pull as like tinyurl.com/abok-chap21 that starts with Half-Hitch(terminating) forms of security for nip positions and evolves to Timber even with the preferred fig.8 style, 'bull-nose' of Round Turn(RT) around Standing...

    Bend radius for rigging

    Dynamic changes in where arc bends as an impact vs. change factor at rest. Somehow as like terminating vs. flowing electric, water, air etc. thru their force channeling devices. Force going to arc vs. cranking around it.

    Overthinking, a Minimal Friction Hitch model

    TY/YW, i don't have every chapter so marked of venerable tinyurl.com/abok-online / the knotting bible, but did mark chap21 as so often used and can sit down at any computer and jump in. There is very natural progression of thoughts/forms extending from previous starting with Half Hitch, that...

    Overthinking, a Minimal Friction Hitch model

    No have not, see that as a dizzying wormhole chase. Am not formally trained, beyond some trig when also training in gymnastics to apply numbers and feel them somewhat too. . i consider a right angle pull on host as a 1D directional force pull, 'lengthwise' as 2D(1D for grip, another D for the...

    Overthinking, a Minimal Friction Hitch model

    Linear Direction is own geometry quantity that persists from input , even after linear conversion to radial arcs of rope device that force ports thru. i find these things to be true, and have given me truest answers in my searchings over decades. For i have purposefully and constantly worked to...

    Overthinking, a Minimal Friction Hitch model

    Wow ty Dan Thorton, that puzzle piece intersects exactly to where i go from "Half-Pro" to "Double Half Pro" (kinda making fun of naming as i do), following naming of another full wrap around after workhorse Round Turn upgrades to Double Round Turn(4th wrap around would be Coil by this naming...

    Overthinking, a Minimal Friction Hitch model

    Linear, focused axis of single dimension (also as sole benchmark/cos rest is measured from), vs. Radial, dispersed axises broken out to now 2 dimensions(from single linear 1D benchmark), is always of great importance to consider. This matters mostly to architecture loaded rope has, but then...

    Wedges or Rope?

    i think, The compressed part of the hinge is the actual common shared pivot as bench mark to all other force points measurements. Try to see (in sound, solid, monolith unit) as if tree on hinge is weightless framework; >>except for a cannon ball of weight called CoG, within framework perimeter...

    Rigging Prussik

    YES. Blake's, Tautline, Open/1 leg pull as input to Prussic(ABoK Lesson#481) shown for model_A of Equal tension rigidity and diameters. _A as an open/single input leg at full tension rigidity matching host of same diameter. _B as closed , 2 leg pull so half tension rigidity onto matching host...

    Rigging Prussik

    Concept: In round on round, grip around is one thing, but grip displacing into more powerful and proper. If pull from both ends of Friction Hitch as divided inputs of half load >>need smaller/denser to bite into the full loaded rigidity of the host lifeline, but the half load powered Friction...
