The composite beam shown below is made of steel (A) bonded to brass (B) and has a cross sectional dimensions of 250 by 175 mm. If the allowable bending stress for the steel and brass are sigma_allow, st = 180 MPa and sigma_alloW, br = 60 MPa, respectively, determine the maximum moment M that can be applied to the beam. E_st = 200 GPa and E_br = 100 GPa.
