Path of the rod tip as it goes to basic loop forma

[Marc LaMouche]

There's so much rotation behind Pauls motion that this hardly qualifies as anything except a cast that runs along a rail

:laugh: :laugh: :laugh: :laugh: :laugh: :laugh:

Makes me laugh out loud too :laugh: . Did you notice the hand position at the end of the rail. If it had been pointing straight up that would change outcome quite a bit I suspect. Excellent linear hand path though, very straight indeed.

I do not know what "basic" would mean as it applies to loop formation

Me neither Gordy....

.....no doubt Frank will be able to enlighten us..

The tip path is primarily convex throughout the entire stroke. There is no escaping that fact.

Apart from when its primarily concave presumably...?

[Stoatstail50]

Is there any part of any of the tip paths in your drawings that is the result of translation Frank ?

Interesting phrasing. Give the basic loop form when would the tip path be primarily concave ?

[Stoatstail50]

When its on a drawing ?

[Frank LoPresti]

Exactly....but only when the caster causes the rod tip to move in that path as a result of a few different things.

[Stoatstail50]

What are the different things ?

[Frank LoPresti]

I think we have covered the 3 main issues and 2 minor issues extensively already. And no, no matter how many times you ask me I'm not going to repeat them either :p

[Stoatstail50]

What.....?

Crikey.....3 big things and 2 little ones to make a concave tip path that "goes to loop formation", and only angular acceleration and arc to make a convex tip path that "goes to basic loop formation"....that's three extra things, loads more things in fact... :oh:

[Frank LoPresti]

The good things that happen to good loops are a result of two things that allow the tip path to remain on a fairly narrow convex tip path. Those same two thing can become bad things in several different ways and cause the tip path to track concavely

[Stoatstail50]

So would the other three things effect the convex path too or is it just the concave path that they influence ?

Or, is it really just two things that cause both tip paths by interreacting differently ?

[Frank LoPresti]

I'd say that both actions control all aspects of tip path as it goes to loop formation.

[Stoatstail50]

Back to only two now then ?

...."the 3 main issues and 2 minor issues" don't come in to it anymore...good job you didn't say what they were again, that would have been very confusing for everyone wouldn't it ?.

[Frank LoPresti]

Hi Mark,

No not really. All three are similar to each other as to their outcome on tip path as a result of angular acceleration Kinda boring, I know.

Cheers,

Frank
