Now, lets displace the Center Of Mass of the club head from the axis of the shaft. 2 additional pieces of Physics are introduced. Toe up/down and torque.
1. with the COG thailing and on the plane we have toe up when accelerating and toe down when decelerating.
2. as the COG leaves the plane of the shaft we have toe down equated to radial force and torque- laging (tending to lay the COM back-open if above the shaft plane) when accelerating and leading(tending to have the COM pass the shaft- close of above the shaft plane- Roll under if COM is below the shaft plane (Driver as example)) when decelerating.
All making the dynamics a computer learned event.
ie. learn a motion then let the computer learn how to hit the ball.
I include some shaft dynamics data as illustration.
PS.
This data shows that the pro's have a forward bend in their shaft at impact- Throwaway- I think so, Also a loss of effective Club Head mass. But lets hold that analysis for another post.
