This light on the subject might only be a flicker instead of a quasar, but I’ll do my best. I’m not a Doctor of Physics, I just play one on T.V.
First of all, we have to talk about load. When a golf club is in any position other than hanging perfectly perpendicular to the ground, there will be a load (force) placed on the shaft that causes the shaft to bend. I think of it as gravity having leverage on you. It’s been said that when a fly lands on a railroad track, the fly bends the rail. To what extent I’ll never know, as it’s almost immeasurable. So, what forces are acting on the club? Gravity is one. Pressure created by the golfer is another.
Imagine the golfer that takes the club to End and also has the club parallel to the ground. Also imagine that the clubhead is a lead weight. When the shaft is parallel to the ground and perfectly on plane, the golfer has loaded the top of the shaft. The golfer feels the heavy loading of the shaft against the 1st knuckle of the 1st finger, especially when he changes direction. See 10-11-0-3 for the Swinger’s Rotating Lag Pressure Point. The Right Forearm position supports this loading of the Clubshaft (Secondary Lever Assembly). So, the Right Forearm position must be such that the arm can support the loading of the Clubshaft.
On the other hand, imagine a Hitter that takes the club short of Top. The shaft position that I want you to imagine is a shaft that stands perpendicular to the ground from the face-on view of the golfer. But from down-the-line, the Clubshaft would be perfectly On-Plane. The lead weight would now feel like it was falling behind you. In other words, you would be loading the side of the shaft. Therefore, the Hitter feels the pressure in the pad of the 1st joint of the 1st finger, the Fixed Lag Pressure Point. The Hitter is supporting the entire Primary Lever Assembly (the Left Arm and Clubshaft) with the position of the Right Forearm.
If you take a wet mop (don’t hurt yourself) and position it as I’ve described in each case, you’ll feel the load, and you’ll find the Right Forearm’s roll in that Loading Action.
I hope that clears some of the fog.
Thanks for that. That's as clear an explanation as I've heard on this subject. Maybe I was just ready to hear it?
