The aluminum and steel pipes shown in figure are fastened to rigid supports at one of their ends and to a rigid plate 'C' at the other end. Two equal loads P are symmetrically applied on the plate. If load P= 48 kN and area of Aluminum pipe A6000mm and modulus of elasticity of aluminium pipe E = 70 GPa and modulus of elasticity steel pipe Esteel = 200 GPa and of A = 600mm then the value of stress steel in steel pipe will be
