2.A timber block 250 mm square is reinforced on each side by a steel plate 250 mm wide and t mm thick. Determine the thickness t so that the assembly will support an axial load of 1200 kN without exceeding a maximum timber stress of 8 Mpa or a maximum steel stress of 140 Mpa. For timber, E = 10 x 103 Mpa; for steel, E = 200 x 103 Mpa.
