Bowling ball axis planes

Post by Jthom757 »

Silly question. Why is the pin on a bowling ball considered the x axis? I guess each industry has different rules for denoting planes.

You guys are awesome. Thank you.

Starting the ball rolling just for fun.
Not a silly question at all.

Hope my reply is not silly ...
Guess-timate ...

Your question struck my curious bone.
I did not know the answer, so I tried to find it.
Did not find any bowling ball specific definitions "yet".

The x-axis is deemed "the independent variable", thus it does not depend on any other variable in an equation.
The pin is the top of the weight block, theoretically right through the center. Being part of the ball it's not going anywhere and not dependent on anything else.

I believe a ball with a weight block has 2 happy places that it can rotate around.
The analogy would be an "American style" football either rotating end over end like it was kicked and a spiral.
May all beings everywhere be happy and free,
and may the thoughts, words, and actions of my own life
contribute in some way to that happiness
and to that freedom for all.

I've seen the football analogy in several places over the years. :)
