>>> You don’t need me to tell you this, but you are a good man.
You piss me off sometimes when you ignore me, or answer for me, or give up on a discussion by “agreeing to disagree”, but two things I am indebted to you for – you have taught me, and you have allowed me to have a voice.
“I find no discrepancies in what I stated and the principles contained in http://www.batspeed.com/research08.html & http://www.batspeed.com/research10.html. Therefore, it would be helpful Ray if you would point them out.”
“Torque is the result of forces being applied to the bat from opposing directions that causes an object (the bat) to rotate about a point BETWEEN the two hands.”
the figure in the lower right hand corner shows a batter with green arrows for the top and bottom hand that I assume are indicating the direction of force for each hand, and from the picture, one would also assume that they are applying force from opposite directions “about a point BETWEEN the two hands”.
you give as an example:
“when loosening a lug nut with a 4 prong tire wrench, you push down with one hand while pulling up with the other (torque).”
Again this is an example of two hands applying force in opposite directions about a pivot point BETWEEN both hands.
I don’t see these as examples of an “oar lock”.
If I were to envision an “oar lock” example, I would not see a pivot point between the hands, rather one hand acting as the pivot.
Oar lock = pivot.
Pivot = one of the hands.
Oar lock = one of the hands.
“The right hand would then be serving the function of the oarlock.”
I mean it’s your website, and your theory, but don’t you see how confusing this can be to a reader. <<<
Thank you for the compliment and I agree there is some ambiguity in how I have described the position of the axis the bat rotates around. If I were to sum it up, I would say that during middle portion of a good rotational swing, the axis is more between the hands. -- If, during initiation the batter is applying THT, the bottom-hand remains more back at the shoulder as the top-head is pulled around it. Therefore, the axis would be closer to the bottom-hand. – If the batter uses BHT to bring the bat to contact, the bottom-hand is being pulled around a slower moving top-hand (the “hook” in the hand-path) and the axis is closer to the top-hand. -- If the batter uses linear extension mechanics, the batter is constantly trying to drive the top-hand past the bottom-hand and the axis will be closer to the bottom-hand from initiation to contact.
