Physicis / Convex-Concave

Walter & Group....

Note the first attachment from Server Sadik.  I found it best to print it out and study it carefully.

The second one is important, I think, because in it I've stated some of my recent understandings of Server's work and have asked a couple of key questions followed by his answers.

The third is a message from Ally Gowans containing discussion between him and Server.

Attachment four... from Walter Simberski

From Michael Jones :

Gordy:

I got an almost perfect score on my CCI exam, but confused Convex & Concave.  Mac Lord indicated that concave means that the rod tip path is such that the rod-tip & line path follow the shape of a rainbow or "cave opening", where convex is the "U" shape associated with adding too much power for a given casting stroke length.  In reading your (above) descriptions of Convexity, I am wondering if: you and I share the same definition, or if we are both mistaken???

Michael ...   The questions involving the words, "CONCAVE" and "CONVEX" are often momentarily confused as the candidate takes an exam.  Even those who know exactly what they mean sometimes confuse them.  I have been guilty of mixing them up when quickly preparing a message in the past, for sure.

CONVEX:    Examples would be the rainbow or an outline of an exkimo's igloo.  A path which rises, then decends.  A dome.  Shape of a mountain.  Path of the rod tip which rises, then falls.  A "U" turned upside down.

CONCAVE:  Shape of saucer.  A path which decends, then rises.  A dome turned upside down.  Shape of a hole in the ground.  Path of a rod tip which dips down, then rises.  Shape of a "U".

From Walter Simberski:

Gordy,

I appreciate the time and effort people have taken to respond to my
previous ramblings. I've attached some questions/comments to Bruce's
comments.

Could you forward his Rod flex-RSP.xls attachment please?

Thanks
