The distributed loading is supported by the three suspender bars. $AB$ and $EF$ are made of aluminum and $CD$ is made of steel. Each bar has a crosssectional area of $550m{m}^2*E_{st}=200$GPa,$E_{al}=70$ GPa. Assume ACE is rigid.

$($Figure $1)$

Determine the maximum intensity $w$ of the distributed loading so that an allowable stress of $({}_{\text{a}\text{l}\text{l}\text{o}\text{w}}{)}_{st}=180$MPa in the steel and $({}_{\text{a}\text{l}\text{l}\text{o}\text{w}}{)}_{al}=94$MPa in the aluminum is not exceeded.

Express your answer to three significant figures and include the appropriate units.
