Ron,
Points of clarification (adding to the confusion?). COA=Middle of Support in regards to
ground forces. COA is the center of a cantilevered axle in both A/P and M/L directions of articulation. Ground forces converge upon and are transmitted to the COA through a central point of "weight bearing" in the center of mass of P3.
Extra credit: What is the common name for the central point of weight bearing in the center of mass of P3?
