> When you pull on the handle of a ‘torque wrench,’ you get a ‘torque reading’ of the opposing force offered by the nut – the tighter the nut, the greater the opposing force. The same is true for the “oarlock” when rowing. When you pull on the handle, the oarlock is offering the opposing force required to torque the blade through the water. If you think not, just remove the pin from the lock and see what happens. --- You could apply torque to the blade by holding the pin still with your right hand while pulling on the handle with your left. The right hand would then be serving the function of the oarlock. Believe me, you will need to push hard with the right hand to keep the pin still as you pull back with the left.

Good answer.

But this is not what you say at:


>>> This "pulling back" of the bottom hand as the top hand is being "driven forward", generates a tremendous amount of TORQUE on the bat. <<<

And not what you show in the pictures at:
