nmgolfer,
Since you are firmly denying credence to my ideas I am obliged to expose the fallacy in your arguments.
You argue that:
“Centrifugal and centripetal share a common line of action and by the principle of transmissibility are an equal but opposites pair (action/reaction). Therefor they/it cannot cause a torque.”
Let’s analyze this statement more closely since it involves a very fundamental error made quite frequently, even by those with a background in engineering or science. Fig1 shows pictorially, with a simple arrangement, the argument employed by nmgolfer. On first look it appears that nmgolfer is correct, yet he is totally wrong.
Anyone with a basic knowledge of physics is aware of free-body diagrams. Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.
Figs 2a and 2b show these free body diagrams for our situation. There is only one force acting on the point mass M and there is only one real centrifugal inertial force acting on the ‘crooked’ segment. Gravity is ignored.
In Fig3a shows the decomposition of the centrifugal force and Fig3b shows the resultant centrifugal toque acting on the ‘crooked’ segment. People will likely recognize the cog of the clubhead in our simple setup.
Hence, in conclusion, I have shown very clearly nmgolfer’s argument to be false and moreover I explained clearly the reality of the existence of a true centrifugal torque operating in a golf swing.
There is nothing fictitious about my arguments as used. There is no invoking of some mystical non-Newtonian and or imaginary “centrifugal torque as nmgolfer's claims I do. On the contrary I simply used common high school physics.
The other arguments in your post are equally basicaly wrong. Just hang on, you won’t miss anything waiting. When finding some time I will come back to your post and decorticate it with delight to show the errors made.
Nice Try But No Cigar.
