I suppose I can assume that N acts thru the fulcrum even when the horizontal arm is on the table & therefore, ignore it. Otherwise the equation becomes useless for my purpose.

Yes, N is the force of the table opposing that of the weight of the resting lever arm when the latter is not balanced by the raised arm.

My model is a lever on a table top. One arm is horizontal on the table, while the other arm is raised at an angle alpha. I'm assuming the weight of the horizontal lever (F) acts at its center of gravity at a distance f from the pivot, while the weight of the raised lever (W) acts at its center...
