Rings/Thimbles etc. became new as i became old and was playing with clevises as Daniel shows going into that time.
.
i had this monster new clevis found in stuff from local phosphate mines.
Wet ground and sanded few numbers off of the 'eye' until smooth and nylon stocking wouldn't hang up when dragged across.
Then gave Round Turn(RT) that fed to side or higher to keep RT from crossing self.
Kinda like overhead Porty of frictions on a metal heat sink.
.
It is the rotational degrees of contact X friction values of the mated surfaces that give (compounding) brake force
>>NOT distance of radial contact as eye tells you
>>Linear frictions calc by distance, but radial frictions compound by degrees.
Eye is interpreter that feeds to brain, a fact leveraged by sleight of hand, tricky pictures etc.
>>good to train brain when to re-interpret , to possibly over write what has been handed.
Larger circumference doesn't give more brakeForce , but rather supports rope thru softer arc to maintain more strength efficiency, and less concentrated heat byproduct, and more heatsink if metal host mount.
.
This was for heavier overhead loading, and did not get thru 1000 permutations before my wings were clipped

!
>>steering away from heavier stuff in the end.
>>so not something have pushed out a lot etc.
Support to clevis should TERMINATE on the support, not redirect down to ground etc. for minimal support loading.
If any length between support and clevis, the side force effects can be seen as more in jointed stages, but pretty much the same at end.
.
Started with mid of throwline piece reeved/threaded thru cotter key eye , then around open end of key
>>but in time that extra safety seemed mostly superfluous, as device was made to take all kinds of abuse in enviro bought for.
But did replace key few times to keep tight as possible in usage, as better than jamming key thru to eye.
.
The hang on control side and lift on load side preTightening, invokes bodyweight, physical effort + equal and opposite of physical effort.
>>So, has 2 adjustable input parts: bodyweight and effort
>>so can hold a built up tension at bay with efforts + friction, and then impact with bodyweight to tweak more tension
>>or sometimes impact with both at some time, or bodyweight first with effort chaser to keep moving etc.
Whatever strategizing, recognizing and leveraging as separate functions can help immensely on high end of range
