Questions on Server's comments

Server....

 

I'm not an engineer....but have a lifetime scientific background, so I'm not totally in the dark on physical parameters.

 

While I disagree with some of your statements, I can keep an open mind and learn.  The statements which cause me to wonder are:-

 

1.)  Your comments on Shane's 3rd paragraph which I thought made good sense and appeared to represent, to me, what I've seen in the casting videos.

 

2.)  The idea of acceleration not being increased by human motion, "at will".  (Intuitively I feel that statement is simply not true.)  If I, for example, start from a point of minimal acceleration as I throw a baseball, and increase to my maximum acceleration before releasing the ball, have I not increased my acceleration ??....Does my golf club swing not represent increasing acceleration of the head of my club as it approaches the ball on the tee.....as a direct result of my physical effort ??  That seems to me to be more than simply acceleration of the head of my club, but increase in the RATE OF ACCELERATION for a brief period of time prior to deceleration.

 

3.)  The concept of maximum acceleration of the rod tip at the point of maximum load doesn't explain what I understood Bruce Richards and Noel Perkins found in their studies using video techniques coupled with the, "Casting Analyzer".  They found maximum rod tip velocity between the point of maximum rod load and the RSP.  To me that suggests acceleration of the rod tip after the point of maximum load.  Shane's statement of the rod tip lagging behind the hand as the rod is loaded and then increasing in velocity well explains what I've learned and what I see. 

 

4.) I DO see the tendency of the motion of the rod tip to, "throw the line toward the ground" after RSP during counterflex.

 

5.) Your comments on torque make good sense, to me.  One cannot have a so called, "casting arc" without that. Added to this is the linear movement taken by the hand during most casting strokes.

 

Could you give us some peer review journal references on these subjects ?

 

Thanks !
