Thanks BerntR

Perhaps my post's title or question is incorrectly worded from a science point of view then. When I say CF perhaps I should say Radial Force or Rotational force or some such thing.

I think I get what you are saying in last paragraph. So assuming we are on an Inclined Plane somewhere in between vertical and horizontal, an Angled Hinge will tend towards the characteristics of the closest plane be it vertical or horizontal. Is that what you mean?

In that case, Homer's string demonstration, didnt/couldnt display horizontal hinging but rather an Angled Hinge.
