Two solid bars support a load $P$ as shown. Bar $(1)$ has a cross$-$sectional area of $A_1=3250m{m}^2$ and an allowable normal stress of $115$

MPa. Bar $(2)$ has a cross$-$sectional area of $A_2=4350m{m}^2$ and an allowable normal stress of $135$ MPa $.$ Assume $x_1=2\mathrm{.}0m,x_2=3\mathrm{.}2m,y_1$

$=1\mathrm{.}5m,$ and $y_2=2\mathrm{.}4m.$ Determine the maximum load $P_{\text{m}\text{a}\text{x}}$ that can be supported by the structure without exceeding either allowable

normal stress.

Answer: $P_{\text{m}\text{a}\text{x}}=$
