Jack. In your definition of torque, I am assuming that your answer is YES to my question. (And since yes is your answer, I will go into detail.)

1. If we assume torque exists, we also have to assume that there is a "whip effect" in which the bat actually bends during the angular acceleration.

This bending of the bat bat would make sense and go in line with your argument that a tremendous amount of stress is being put on the bat because of the wrist action involved during THT and BHT.

But the question is can stress be put on a bat that is made of maple, hickory, or aluminum? Those type of bats do not have the same bending (spring board) properties as ash. Therefore, how relevent is torque with those type of bats?






And if the modern move is to use maple bats over ash, does that mean that the mass and or hardness of the bat is much more relevent than the initiation of torque during the swing?
