1. The problem statement, all variables and given/known data http://imgur.com/dMw79w1 [Broken] The image contains the problem as well as the answers to the previous problems. 2. Relevant equations Net torque = 0 3. The attempt at a solution First, I set the axis of rotation to be the bottom of the table (where it goes through Fx and F0) τdue to downward forces = τdue to upward forces τvase + τtable + τcat = τdue to Fy (Fy (the solution to Fy is in the image) WvY + WtLy/2 + WmaxLy = Wt/2 + WvY/Ly Rearrange for Wmax: Wmax = Wt/2Ly + WvY/Ly2 - WvY/Ly - Wt/2 The answer to the question is: Wmax = Wv(1 - X/Lx - Y/Ly) I don't know how to obtain this answer from my answer above.
