Question

Provide all necessary solutions. Do not round off unless it is the final answer.

The distributed load w is supported by 3 suspender bars as shown. AB and EF are made of aluminum and CD is made of steel. If each bar has a cross sectional area of 460 mm^2, determine the maximum distributed load w (kN/m, 4 pts) so that an allowable stress of 180 MPa in steel and 94 MPa in aluminum is not exceeded. Use Est = 200 GPa and Eal = 70 GPa. Assume ACE is rigid.
