Re: pool table physics



Thanks for the help, Tom.
Isn't it a wonder how we are able to go through life
without such information available???

Herb,

I actually the question about the size and
weight of que balls a while back when I was working
out an example problem for my class. I sent out a few
Emails. Here is the words of "the experts"

Blache Quenville of "qball.com" replied:

"To answer your questions, a standard cue ball for
American pool games weighs 6 oz. and has a diameter of
2.25",
which is true for all balls in the set. The only exception
would be on a coin-operated commercial pool table, where
the
cue ball must be different so that it will not fall into
the same area as the other balls. In this case the cue ball
can be 2.25" and heavier (because it has a metal core) or
2-3/8" (also heavier)."

Don Wright of the Billiard Congress of America replied:

"BCA Specifications as follows:
Molded and finished in a perfect sphere in the following
weight and diameter
Pocket Billiard Balls
Weight: 5 1/2 to 6 oz..............*Diameter: 2 1/4"
*Diameter tolerance +or- .005"

Does this mean that each of the pool table holes only allows the
smaller balls to fit through and the larger cue ball can
never sink into
a hole??
If so how much larger must be the cue ball so it can be easily
retrieved after a scratch?
