Which one would go farther?

You can watch the whole thing or you can start where I've book marked it. Interesting science, though.

the ability to blindly trust some random internet dudes "test" findings?

I think you have a Zepp right? The least you could do is post the graphs from the test as proof that this actually happened. Or is all this based on your bionic vision?

Your in Cali, right?

Next time you come and play in AZ let me know. Those who learned the game from Google will never get it, you are crippled and will never understand fully, hopefully your daughter(s) will be able to learn from coaches who get it, or sadly...they too will not make it. This is fact, seen it hundreds of times.

i take it that this response means you will not be furnishing any supporting info for your claims?

I wouldn't let these protractor guys bother you, those who coach and played the game know that your right.

I did another test this morning, it was a perfect opportunity. I had a kid 5-11" 220 lb (college player), and a 4-11" 100lb slapper (high school sophomore). The slapper had equal batspeed to the big kid +/- 1. Same bat, the big kid is hitting the ball 250" easily, and the slapper was hitting the ball 180', never came close to the fence.

The Protractors are missing something very important here, what is it?

No, they are not missing anything. It's you who is missing something. Either your experiment variables were way off, or you never did it. Either way, I side with true science. The following equation has been proven to be true.

BBS= qV[SUB]pitch[/SUB]+(1+q)V[SUB]bat[/SUB]

BBS = Batted Ball Speed
q = Collision efficiency
V[SUB]pitch[/SUB] = Pitch Speed
V[SUB]bat[/SUB] = Bat Speed

Same bat used and the bat speed was the same.......really.

This video made this thread worth it for me. It cleared up a couple of misconceptions I had. Thanks.

What really interested me was the different wave pattern between a wood bat, which moves like a sine wave, and aluminum & composite bats, which squish the barrel for their wave patterns. Yes, I watched the whole thing. Very enlightening.

I would think the ball is in contact with the bat for less time on a handle hit and that the ball does not compress as much. As for flexing more on an end of the bat hit I don't know either. ill have to check the studies but I would guess that when you hit the ball on the sweet spot you are hitting it exactly 1/2 the way between nodes so that you are actually exciting the vibrations such that the sweet spot sees the max amplitude and can bounce off the bat. That is why they feel so sweet and don't sting the hands, the bat is excited perfectly so the hands are at a node and the ball is being launched with max energy transfer.

An end of bat hit causes a lot of flex and probably a higher frequency, but I think the amplitude of the actual bend is lower.

I don't think it is as simple as the further out you to the bigger the bend, it is more subtle and it depends where you "pluck the string". If you are familiar with a guitar, think about plucking hard at the end of the string vs plucking right In th middle or on a harmonic.


is this answer bland enough for all the sensitive FNGs?

Thanks.

Efficient energy transfer is good. Thats what we try to do. On a ball hit off the end of the bat where does the energy go that isnt transfered to the ball? The bat, right? What effect does that have on amplitude/frequency?


I see a lot of flex in the bat when the ball is hit on the end. Sometimes wood bats are broken on hits off the end. Thats high amplitude! The bat tends to break on the handle. Hmmmm. Do you think the bat would break on the handle if you threw the bat at the ball and hit one off the end?


Good talking to you JJ

Do any of you guys have the Zepp system? Ever went out to just see what bat speed it would take to hit a softball 220'? Would be Interesting with different size bats

No, I want to show you in person, then you will believe that there is different levels of energy transferred to the ball or should I say different levels of energy dissipate or lost into the bat....when you say things are equal. You will see the same batspeed to the ball, and then see one kid demolish the ball, and you will see one barrel nearly come to a stop at impact (exaggerating, but you can really see the slow down)....and you will see the ball fly different distances by a large margin.
