Part A The rigid beam in (Figure 1) is supported by the three suspender bars. Bars AB and EF are made of aluminum and bar CD is made of steel. If each bar has a cross-sectional area of 450 mm, determine the maximum value of P if the allowable stress is ( allow)st = 210 MPa for the steel and (Callow)ai = 140 MPa for the aluminum. Est = 200 GPa, E l = 70 GP Express your answer to three significant figures and include appropriate units. 1 НА ?
