Thanks for replying. It doesn't help me understand the hitter's release physics. I can imagine how the centripetal pull of the lever assembly causes the linear thrust of the right arm thrust (due to active straightening of the right elbow) to produce angular motion of the clubshaft. However, what controls the speed of release of the clubhead in a hitter's swing? Is it entirely due to the release of power accumulator 1, or are other factors involved. Also, how does a hitter produce a varying size of the endless belt pulley if his right arm thrust force is always linearly-directed towards the aiming point?

Jeff.
