if the area is rounder then it will have less clamping force to resist tail movement, because the load/force is spread over two diameters.
Good try,,, but you would nt believe I will swallow it before I examine it, would you ?
At THIS area, there is no clamping force by the nipping turn ! There is only a U turn around the outer surface of the rim of the nipping turn - either around one rope diameter, kicking and screaming, or around two rope diameters, happily following a wider curve that leads the working end into the centre of the nipping turn. In BOTH variations, the Tail is relieved by a great amount of pulling force at this U turn ( as it happens in every Tail after it has made the U turn around the Standing end we call "collar" ), and only THEN it goes into the heart of the nipping turn, where it is squeezed by it, and immobilized by its contact with three other two segments there. ( We should notice here that the Tail and the eye leg of the Tail meet in this central area at a right angle - the right angle any two segments should meet, in order to be immobilized most efficiently ). So, the clamping force acts at the centre of the nipping turn, NOT at the outer surface of the rim of the nipping turn, which is encircled by the U turn ! So, regarding the clamping force, the diameter of the U turn plays no role at all ! There is no advantage having a sharper U turn there rather a wider one - but there are disadvantages, which were explained in my previous post.
In fact, if the interested reader has even a quick look at the two variations, he will realize that there is no difference in the nipping turn or the location of the Tail in the point where the clamping forces do act on it...See the image you have submitted in the other post : One can hardly notice which variation is presented - because this "front" view is almost identical. However, when I look this poor anaconda having to bend so much before it enters into the hole where it will be clamped, I wonder why it has to suffer this torture.
Now, it would be great to actually
measure the forces on the Tail in the two variations - or use such a slippery material that would possibly reveal any small motion in the weakest of them. Otherwise I will not be convinced by the moving attempt to protect your first child, and ignore the second ! I can only see a sharp and a wide U turn, around the rim of the nipping turn, or around the same rim of the same nipping turn in the same location, PLUS around the eye leg of the Tail - and we all know that the possible capstan effect on the segment that makes this U turn does not depend on the diameter of the drum. A wider turn may not relieve the Tail more, but it also does not relieve it less.
version one is a bit sleeker and compact than the TIB version ....
You know the joke with the farmer and the two cows, the white and the black one...(2).He always praises the black, even if he has to admit that their qualities are, in fact, identical. You are cautious to use this "a bit", that is true, but even this does not tell the whole story...Because if a stiff springy Tail resists this painful bending, the U turn will remain an "eye wide open", so, actually, the total volume of the knot will be larger, not smaller ! It will be sleeker and more compact, ONLY when and after it will be locked, and ONLY if the material is not very stiff. Otherwise, it will not, and I was talking about this "otherwise"...
Version one:
Easy to remember how to tie as well. Very easy to inspect. Works great with stiff, static ropes as well. And when you're done it unties easily .....
"Oh, the black cow...Such a superb animal...It produces the best milk in the village..." " And the white cow ?" " The white cow ? It produces exactly the same quality of milk as the black one..."
BOTH versions are tied in the same number of tucks, in almost the same way. BOTH are easy to inspect - because if the one IS easy to inspect, so will be the other ! They are almost identical ! BOTH work great with stiff static rope - because if the version one does work great, the version two will do as well, and even greater ! And when you are done, BOTH will untie easily. ( Provided that the version one, with the Tail-made spring, has not become untied already !

The city guy decides one morning to go out for a walk in the country. As he is ambling down the sunny country path, he comes across a simple farmer, tending his two cows.
"Good morning, farmer," says the city guy.
"And good morning to you, sir," says the farmer. And he pauses, and waits.
The city guy, out of his element, thinks that probably just ending it there isn't enough. Struggling for a further topic, he says, "Those are some fine cows you have there."
"Oh, yes, the black cow is a lovely cow, she is," says the farmer.
"And the white cow?"
"Well," the farmer pauses, "... yes, I suppose the white cow is good too."
"Yes, they certainly look fit and healthy," says the city guy.
"Indeed, the black cow is the healthiest I've ever had! Never needed the vet, full of life!" responds the farmer.
"And the white cow?"
"Well,... yes, the white cow is pretty healthy too."
"So I suppose they give a lot of milk then?"
The farmer beams. "You should see the black cow, come milking time, she's full to bursting with the creamiest milk, she is. Oh yes indeed, the black cow gives a lot of milk she does."
"And the white cow?"
"Oh, well, yes... I suppose the white cow gives a lot of milk too."
The city guy doesn't really know where to go with this. The farmer seems to really have something special for the black cow, even though the white cow seems just as good.
"You know, farmer, I don't mean to intrude, but it seems every time I ask you really favour the black cow...."
"Well, isn't it obvious?" asks the farmer, "The black cow is
MY cow!"
"Ah, I see. And the white cow?"
"Well, yeah, the white cow is mine, too."
