This stick sits horizontally on three supports as shown in the figure below and remains at rest. Find expressions for the three forces from the supports; is it possible to uniquely determine all three support forces in terms of M, g, and/or the length quantities drawn in the figure? Either way, based on the expressions you find, do you obtain expected results in the case where the middle support is removed? d₁ d2
