The structure can carry a maximum load of $\mathrm{P}=514 \mathrm{kN}$.

At this load, member (1) has a normal stress of:

$$\begin{gathered} {\mathrm{\sigma }}_1=\frac{{\mathrm{F}}_1}{{\mathrm{A}}_1}=\frac{485.070 \mathrm{N}}{3,080 {\mathrm{mm}}^2} \\ =157.5 \mathrm{MPa} \mathrm{O}.\mathrm{K}. \end{gathered}$$

and member (2) has a normal stress of:

$$\begin{gathered} {\mathrm{\sigma }}_2=\frac{{\mathrm{F}}_2}{{\mathrm{A}}_2}=\frac{348.750 \mathrm{N}}{4,650 {\mathrm{mm}}^2} \\ =75.0 \mathrm{MPa} \mathrm{O}.\mathrm{K}. \end{gathered}$$
