With just one hand on the bat, the wrist has freedom of movement to apply torque over nearly the total range of the swing. But having both hands on the bat restricts the range of wrist movement. Torque in the two-handed swing is mostly supplied from the push-pull action of the arms.

hi jack,

your swing test from a stationary position intrigued me. i proposed a similar (but not the same) test to paul.

under the topic " 'VOODOO' physics" which ran from 12/15/2000 thru 12/19/2000. my post - 12/17/2000 at 3:29 p.m.
