>>> I would personally like to see some more testing for the torque hypothesis,especially what Jack describes as "THT".<<<

Hi Tom

We can start the testing anytime by having everyone involved define the forces acting on the bat that induces angular displacement during initiation (we can later discuss the mechanics that produce those forces). Some have denied that torque applied at the handle is the mechanical principle responsible. But, no one has offered to define an alternative physic’s principle that generates bat-head acceleration.

Anyone who would like to prove torque is not a mechanical principle involved in generating bat speed is welcome to try. They should do so by defining the correct mechanical principle they believe is responsible. -- However, anyone who denies torque without fully defining an alternative – is just taking cheap shots.

Tom, for obvious reasons, a good place to start the testing is with Paul Nyman. Have him define (as I have) the forces the hands are applying at the handle and the mechanical principle that causes the bat-head to accelerate. – Namely, what is the direction of force of each hand during initiation that cause the bat to rotate and define the mechanical principle involved.

I have defined the forces acting on the bat that cause it to rotate about a point as (1) Torque – hands applying force from opposing directions (2) an angular rate of displacement of the hand-path induces an angular rate of displacement of the bat. Have Paul define his alternative definitions.

After Paul responds (if he actually does), you can post a summary of his definition here.
