I know, I was trying to state that there's a difference - a subtraction. You stated that as well. I think I merely didn't state it clearly enough. Partial sums calculate up to the entirety of the upward force. It's vector algebra with forces.

Well Fg + Fn = zero when it's vertical. now the Fa has an opposing force, the force from the ceiling pushing back on the person. Do you want to call that Fnc? So that's another normal force. The person holding the object upright is supporting the object exactly with normal force until they...

Yes. though if someone were searching for something similar and found this forum, as I had, then perhaps some of these replies, mine or others, will help future seekers.

You are both the applied force and the normal force, because the object is directly above you and hence you are 90 degrees from the plane. Thus they are the same force. If you were on an incline, the normal force can be derived via some basic trig. Fn = Fw / ( sin(normal angle) + cos(normal...
