I've been thinking alot about planes recently. If I recall my geometry correctly, it takes three noncolinear points to define a plane. What three points define HK's various planes (ie turned-shoulder, elbow, etc.) in TGM? Thanks in advance!

PS-I've looked in the book, but couldn't find them defined that way.
The Plane Angle is defined initially in 7-6/10-6, elbow,turned Shoulder, etc. and is in reference to the angle between the horizontal surface (the ground and it assumed to be flat).
This Plane Angle is applied to a line that is on the surface, the Plane Line 7-5/10-5. It is defined as the base line of the Plane.
The Inclined Plane Line is parallel to the Sweet Spot Plane Line (which is often considered to be the Target Line or Line of Flight Line and is defined as the Impact Line 2-N-0 which definite lies on the Sweet Spot Plane at all times)
Of the two primary Planes in TGM, the Inclined Plane is the plane the clubshaft travels on and the Sweet Spot Plane is what the Hands monitor the Feel, the drag/lag, motion, etc. (This may be refuted by others). I posted a thread in the lab about the Inclined Plane.

hey martee,
thanks for the response...yes it's those threads in part that have started me thinking about this...i have my own thoughts on what points one uses (or can use) to define these planes...the the named body part (ie turned shoulder, elbow) is one, but what about the other two?...i'd like to hear some other ideas (especially from those who have talked with HK)

HCW, I like you recollection of Geometry class. 3 points define a plane. That's one thing I got between stabbing crap with my protractor. The protractor was multitasker. Weapon. Great for drawing nekkid chicks and football helmets.
I would think one of the 3 points that define the Plane would have to be on the Plane Line. How about the Hands and a point on the body defining the other 2 points?

Word.

i preferred the compass for stabbing, but the protractor did as you point out have, uh, other uses...
well actually if you have a line, you only need one non-colinear point to make a plane...so the question becomes what two points defined the plane line?....
my thinking at the moment for the sweet-spot plane is that the three points are 1) the body definition part (ie turned shoulder, elbow, etc); 2) the impact fix position of the pressure point used for monitoring lag; and 3) the impact fix position of the sweetspot...i'm also thinking there must be a different point #3 for the inclined plane, but i'm not sure what it is...
In Plane Geometry, planes have no mass -- they are shapes in space.
The "three points" you refer to don't necessarily define the shape of the plane. You can have planes that are shaped like rectangles, circles, squares, triangles or any shape.
However, any plane can be defined by any three "coplanar" points -- i.e., three points that are lying on the plane you wish to define. Thus, you can have three points -- A, B, and C -- on a large circle-shaped plane. Lines drawn between the three points would describe a triangle -- but those three points would still define to which plane you refer(as would any other three points on the same plane).
For example, you could describe a street as Mr. Brown's street or, his neighbor, Mr. Green's street. That would identify the street, but wouldn't tell you the shape of the street.
Most people think of The Golfing Machine plane as a huge rectangle -- and, it could be. It could also be a large circle, square, etc. Mr. Kelley never described the shape of the plane -- he only said that it had to be larger than the cirucumference of the club being swung (2-F).
i agree...my thinking was that this plane extended forever above, below, to the right and to the left of the golfer....but as you said, you only have to imagine it being larger than your club circumfrence...

If you read the last paragraph of 7-7, Mr Kelley says "Always view the Plane as retangular (with four ninety degree corners), ...."
