Trying to think of a mechanical model. How bout this kids propeller toy. Imagine the blades as being the shoulders , not the arms. Now imagine another even longer straight piece representing the left arm attached to the left shoulder propeller blade by a piece of string. Upon rotation would not the far end of the left arm piece move the fastest of any component? Uncentered though it is . Incidentally having a string like connection between left arm and left shoulder is a must for power transfer. Muscle tension at that connection is a silent killer..... if you ever lose power under stressful tournament conditions , or in cold weather, check your string connection. Need a big drive ... make sure its string like.
Last part of O.B. comment I didn't talk about above.
There are two (2) vectors we must look at:
1. that points straight out from the center-which will aligne with the shoulders under steady state rotation. (radial)
2. That trails the accelerating skoulder and is only present during acceleration, be it + or -.
The summation of these two vectors locates the "power package" arms hands and club, in general. BUT, we will restrict it to the left arm and #4 accumulator here because we need to keep within managle problem bounds.
The "vector sum" or resultant is of lower magnitude than the sum of the individual magnotudes if there is an included angle. and, the direct is within the included angle at an angle proportionate to the individual magnitudes. ie. You have to do the Trig.
Vectors can represent force, having both magnitude and direction. Nature likes to get/keep things in the lowest energy state. ie. the shortest vector resultant for the conditions at hand.
Good golf (TGM) requires good alignments created by good vectors, when you get moving, the direction and forces in these vectors are what is felt.
You know humans are real good at learning this. BALANCE. we run, walk, start fact, turn fast or slow all sorts of athletic things and all without falling on our face. Well, sometimes we do fall and sometimes we hook it off the face of the earth.
we practice this stuff 24/7 when we a child. how long does it take to swing a golf club? 1 second.
Is this a simple game?
