Very good info; ty!
.
Most precise would take repetitive experiments.
>>But all the same would have lost bet on 1 twist as this stands.
But in real world, with more contacts to load, perhaps linear and not radial faces
>>think best overall bet would be no twist, and never a twist on a contact area if any.
Flat rope goes over bends will, as the deformed axis is the very minimalist flat one
>>round rope stands higher for more leverage against rope device
>>but in making a HH etc. can scrunch, deform across largest cross axis (to linear load down length of webbing)
.
This is most expressed in flat but wide webbing
>>much less so in 1" that is thicker than pure flat and offers less leveraged distance to deform across.
Much less i think in skinny dyneema slings therefore, and cross profile is even thicker as resistance to scrunching
>>
so much so that 2 layers (dyneema folded) is about as thick as dyneema is across>>so squarer to round to maintain more consistent strengths i think in 2 legs thru as Cow, even more so if both loaded/Girth, or with self balancing pulls /Round Sling, choker.
i see this squareness to profile when doubled also in 3/8" Tenex and paracord.
These devices seem to seek best of both worlds:
>> lay flat on a curve host were webbing is better
>> yet deform less with choke around 2 legs as are square as closest linear to round: where round is better!
Round is equilateral/ no leverage preference given/lost at any angle, square is closest non radial to that prescription i think
>>would not lower with webbing, only round from friction and on round host.
.
i also think/have always done: crank web, pinch off, clear spool, crank TIGHTER.
As the spool fills, leverage is lost.
BUT, at finish want at least 720degrees on spool for positive mechanical lock that way
.
In carrying trailers of brush loaded cross ways, we would use 2 straps lengthwise
CROSSED, so if started to slip off to one side, would tighten not loosen...
.
Set straps can be tightened more by bending together some or to side etc.
Radial vs. Linear matters in force as have tried to show;
But is also matters as a choice in the type of medium/device chosen for strength etc.
BUT, Radial vs. Linear matter perhaps most in the host, the shape the material/device then adopts as a structure along with how the knot is tied.
.
Linear rope parts are just connectors, 180 arcs especially lend controls of friction, better nips and in more than 1x180 grips
>>this is something that can be lent in part by the device around self if round but mostly inherit from the traced host.
.
These all lay flatter around host mount where round rope weakens as is not flat, but then if Half Hitch around Self deforms/weakens harsher in flat than round rope. But the Paracord, Tenex and Dyneema Sling when folded are about same size as profile, so deform less scrunched in Half Hitch around self or choke etc. IN this way perhaps the best of both worlds: flatter on host like webbing and about square /almost round when 2 legs scrunched around by another to least deformity/almost round.
