Centrifugal Force stiffens the Swinger's Clubshaft, and that Thrust (and Loading) is Longitudinal. And Body Momentum Transfer (via the Pivot) offers resistance to Impact Deceleration. Muscular Thrust stiffens the Hitter's Clubshaft, and that Thrust (and Loading) is Radial. And Body Momentum Transfer is not available. Hence, only Pre-Stress (via the Right Triceps Muscle Power) offers resistance to Impact Deceleration. __________________ Yoda Yoda View Public Profile Send a private message to Yoda Visit Yoda's homepage!
