Hi All

This is a continuation of the "To Jack" thread.

(Teacherman)
>>> I'm disappointed in your answer. You are careless with our language. You asked me about THT. Then, you respond with an answer about prelaunch torque. <<<

Hi Teacherman

You are mistaken, I have always maintained that Pre-launch Torque is part of applying Top-Hand-Torque. I designated it pre-launch because the batter is applying torque to accelerate the bat-head back toward the launch position before body rotation is initiated.

Are you then saying that you agree torque is being applied during "prelaunch torque?" If not, address my question.

In the Sheffield's pre-launch movements
1) What force, other than torque, do you say could have been applied by the hands to the handle that caused the bat-head to accelerate up and over the knob (as described below)?

"Let us use Gary Sheffield as an example. As he prepares for the swing, he keeps his bottom-hand fairly stationary at his back shoulder. He bobs the bat-head up and down at the pitcher by pushing and pulling with the top-hand. He then accelerates the bat-head from a nearly horizontal position in an arc up and over the knob back toward the launch position.

Teacherman, the shoulders remain almost motionless - there is no reactionary force from rotation. The bottom-hand remains at the back-shoulder - there is whip effect. The bat-head was accelerated from a static position (no momentum), up against gravity by the top-hand pulling up and over the bottom-hand. (Note: The cocking or un-cocking of the wrist also apply forces from opposing directions at the handle.)"

The readers can weigh the worth of your other answers.
