I have a table and I want to get the weight of the table. I only have one scale. I weighed the left side then the right side. I believe this is a simple statics problem but I can't figure it out. I have broken this down into this:
A beam with points A, CG, and B. A is the left side, B is the right side and CG is the center of gravity. L is the length of the beam. Assume the angle of the beam is negligible while pivoting. While B is a pivot, the force on A (weight on the scale) is Fa and the moment would be L*Fa. While A is a pivot, the force on B is Fb (weight on the scale) and the moment would be L*Fb. And while A and B are not pivots then the force at CG would be the weight of the beam and the sum of those moments would be 0.
Am I on the right track?
