Re: rotational and translational into translational
extremely interesting stuff Ray for someone like me that learns from comparative analysis.
Jack talks about low load vs high load situations where load/resistance to rotation depnds on moment of inertia and how this relates to handpath radius. also russell has found that the bat's MOI is the main determinant of batspeed so that plus the trampoling effect give composite and aluminum the advantage over wood.
also,being an arm action is king proponent,I would think the hammer event is more similar to hitting with more front side involvement than discuss/shot/javelin which are all back arm throws.
