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,
Hi Rick,
I'm doing well, thanks. Almost normal (whatever that means

I don't know who labeled that particular stroke a pendulum stroke, or when, but I imagine it served it's purpose back in the day. But I think there's nothing wrong with revisiting old terminology and updating it as we progress. We do that with rules and with definitions of terms associated with rules, so why not in other areas as well?
