The steel and aluminum plate assembly is bolted together and fastened to the wall. Each plate has a constant width in the z direction of 200 mm and thickness of 20 mm. If the density of A and  is ρs = 7.85 Mg/m3, and for C, ρal = 2.71Mg/m3, determine the location of the center of mass. Neglect the size of the bolts.
