Hi PJ2
This is as close to perfection as i can imagine.
"I would disagree that there is no "load" on the airfoil. Wouldn't load be a resistance against a force whether something is held in place or whether it is dead weight plus Nz?"
******************************************************
When viewing a film of an aircraft that tragically lost its airfoil at high speed, I noticed its "vector" as it flew through the air behind the doomed a/c. It was not rising, it was not falling, so much as it was horizontal (and of course tumbling). This is instructive of your comment. The "load" on an airfoil is aft (predominantly), not up, not down, but opposite the direction of flight. So discussions about the relative static loads are moot related to the vertical. The 'lift' is forward with an upwards component.
The wing, in my opinion, is aboard to produce drag as a product of its incidence, the lift comes from the momentum it imparts to the air, due to this drag.
The arrows in the primitive diagram are completely misleading, because there is Rate which serves to rotate all four arrows clockwise, sustantially.
Imo....
