The distributed loading is supported by the three suspender bars. AB and EF are made of aluminum and CD is made of steel. If each bar has a cross-sectional area of 450 mm², determine the maximum intensity w of the distributed loading so that an allowable stress of ( σallow)_st = 180 MPa in the steel and (σallow) _al = 94 MPa in the aluminum is not exceeded. E_st = 200 GPa, E_al = 70 GPa. Assume ACE is rigid.
