Determine the maximum downward force Pmax that can be applied to wedge A that will keep the assembly in equilibrium. Based on the value of the force in link BC, determine whether block C will slip or tip first. At Pmax, what are the frictional forces between wedge A and block B, fAB, and between wedge A and wall D, SAD? The weight of block C is 192 N while that of the wedge is negligible. Draw the FBDs of wedge A, block B, and block C. Label correctly all the forces (especially normal and frictional forces with proper subscripts) and indicate the direction of the impending motion next to each FBD.
