Per Rick, post #206: "Lastly, as to inexact 'anaylogies' the stroke is nothing like a pendulum as the forearm is not a rod & does not 'swing' due do gravity as you have so aptly pointed out."
Rick, I can't imagine anyone arguing that a pool stroke is a true pendulum. I think a better term for it would be pendulum-like, and that's even stretching it. The main difference I think is that the pool stroke is obviously not gravity-driven. We'd have to let go at the top of the arc for it to be gravity-driven, right? Am I wrong about that?
Isn't that pretty much what you were saying?
Maybe, instead of arguing about it, we should be working on formulating a more accurate term for that type of swing.
Hi Fran,
How are you?
Believe it or not, I would describe myself as being an unconvinced non- conformist & hence unaccepting of the arguements that were trying to persuade me to do so & thus became agumentative. Sorry, I know that is not to your & others' liking, including myself, again believe or not.
The quote you reference was in response to Sean picking apart some of my anaylogies that I really did
not mean to be an 'exact' comparison to the 'Piston J- Stroke'. So... I was just pointing out that the 'pendulum stroke' is almost in no way analogous to a true pendulum. A little nit for nat. It was
not the focus of the 'discussion'.
As to the term 'pendulum', I would agree that it is very poor & even 'pendulum-like' is a stretch, as you state.
As to your question, yes, we would have to completely 'relax' & not use any muscles & simply let gravity 'pull' the arm back to perpendicular, at which time, if set up near perfectly, the tip would be at or near tip/CB contact and that would be the limit of force we could apply to the ball. I do not know, but that method might even produce a double hit dependent on the cb /ob seperation as the cue would also be uncontrolled on the other side of perpendicular other than by gravity & the affect of colliding with the CB. I do not know if a human being is even capable of doing that in a conscious state.
In the thread regarding the pull/push aspects of the delivery of the pool cue, I feel that the point was certainly made that 'no one' feels, thinks, or believes that a pool 'stroke' is anything like a gravity pendulum.
Who named it that anyway? It was not well thought out IMHO. Also do you know who developed it as a stroke to be taught?
In any case that is my take, but I defer to the scientists for a totally accurate explanation.
Perhaps, the
Single Hinge Hit would be more desrciptive & user friendly.
However, that is
certainly not for me to decide, as I am
certainly not using it & I would not teach its' finish, except as a last resort.
The last thing I want is another word war.
Best Wishes,
