Shaft Stiffness and efficiency.

[MattPoland]

I would love to see analysis of the influences of speed factors. It would be nice to see results across many different parameters.

Stick Weight: __ ounces
Tip Material: ______
Shaft Material: _______
Stoke Speed: ______
CB Speed: ________

And be able to break down what percent of influence each factor had in the determining the final CB Speed. Like would it look something like this?

Stick Weight: 2%
Tip Material: 1.5%
Shaft Material: 0.5%
Stoke Speed: 96%

Or would I be surprised to find out it’s drastically different?

I cover these effects with graphs here:

TP A.30 – The effects of cue tip offset, cue weight, and cue speed on cue ball speed and spin

Check it out. You don’t need to know all the math and physics to understand the graphs and conclusions.

I would need a secret decoder ring.

Bob and Dr Dave:

You, combined, have the equipment necessary and shooting prowess to actually measure what is correct. I respect your experimental integrity.

Experimental setup::
a) Have the high speed camera measure the velocity of the CB as it leaves the tip of the cue (you are going to need better than 1% here)
b) use a tape measure to measure the distance travelled.
c) hit the CB such that it travels less than table length (to keep the rails out of the measurement.)
d) hit the CB at least 10 times at each combination of offset distance from center and rotational angle (T,L,B,R}

graph CB velocity versus CB distance.

See the graph on page 7 here:

The theory on this is solid. I see no reason to do an experiment. But if you feel the need, go for it.

does this have anything to do with actually playing pool? does knowing this minutia improve one's game?

This will surely help improve someone's game.glad you were so helpful.
