I dont even know if hes talking about poi in the hand or the air
either way makes no sence.

I think he's talking about the change that occurs to the velocity of the head of the poi when it's thrown depending on the weight of the poi:poihead ratio.
Though t be honest I'm not completely sure and may be completely wrong, and would appreciate a better explanation

well i *think* he means when poi curve either toward or away from the direction of spin, and how different weighting of head and body affect it.
i don't *think* it exclusively means thrown, but spun too.
but i don't see how Richee's statements about head\body ratios are reached, cause i'd have thought you'd need to include the effects of gravity, drag (wind resistance), speed of spin and other concerns.
Richee - am i getting close?
there are meant to be pics\animations in Richees post there which *might* make things a bit clearer if i could see them. Can anyone see them?

1 thing though.
What is Fc???
Fourier coefficient? Please tell me it's not fourier coefficient. If it's fourier coefficient then i most definitely DO NOT understand

I believe Fc means 'Force'. So, I think this is about being able to spin the poi body in an arc instead of a line. I could be wrong. The pictures show what I think is force in two different parts on the same passage. So that doesn't seem right. It could very likely mean Fulcrum too. It makes more sence that way... I think it's fulcrum.

imho not shure if the differentiation between the applying forces on the Poi head and Poi body are adequate. I just cant imagine my chains overtaking my wicks
But for the theoretical approach and geekiness factor
- highly appreciated 
Its always good to have people who are thinking in corners where noone thought before
keep on geeking
cheers

hmm, but if you look at poi tails, they follow the poi head, due to lightness and drag.
Depending on how your defining, you could consider the end of the poi tail to be the Poi Head (as it's the furthest part from the handle) and the head bit that the tail comes out of as the middle of the Poi Body.

i agree with andy... experience tells me that your chains stay straight unless you spin pretty slowly.
not sure how you would account for having string with mass, with a mass attached to the end... if it was a rod with mass with a weight on the end then you have a compound pendulum, and the whole thing moves at the same velocity, and you need to work out the centre of mass of the entire thing. i geuss the srting/chain will act like a rod as long as its got enough tension from the mass on the end and it stays tight.... not sure about that though?

Tension force is reverse to contripetal force,
that I've taken to be a base for this concept.
----
Gravity, there is whole part missing between
the resolution and causality.
Part, that describe gravity in vertical and hori-
zontal Poi position that is significant.
----
I've thought for ages, that weighted Poi has
at last same weight, like Poi body.
Prove tells when the Poi head is half weighter.

Richee, please, be a little less cryptic. are you talking about during throws, or during regular spin, or at one point in regular spin, or what?

maybe we should all just do poi with double astrojax.

well, Richee clearly prefers being a little cryptic, i don't think its a problem
i much prefer he take the time to say stuff cryptically rather than not at all.
i think it's a good approach, because amongst other things it avoids people asking meaningless "am i doing this right?" type questions. Clues at broader concepts are more fun to play with than trying to mechanically copy something you've had fully explained.

Monkey, agreed, but when trying to explain a theory, surely it's imperative that people understand you fully, otherwise you risk coming across as a crackpot.

yep ed, im also not entirley sure what richee is trying to describe, from the pictures it looks as if its a double pendulum but from what richee says it sounds like hes trying to model a pendulum and take into account the mass of the string.
he seems to think that its possible for the poi head to overtake the poi body?

what exactly do you mean by poi body richee? i assume you mean the string/chain/sock? maybe not. poi head is surely the wick?

87wt2gxq7,
I thought that there is a mistake, thank you for
explanation.
I meen ,I tried to make a concept of Poi head/body
wight balance from straight Poi.
But according to Mcp note, I'll try to calculate
it from "bow"(deltoid, like astrojax) itself.
Inna whole new thread.
Want to help? (PM)
