Q5) Determine whether the structural system is safe under the loads given in the figure. Cross-sections of all members of the plane truss are circular with diameter of \( 15 \mathrm{~cm} \). The safety factor is \( \mathrm{n}=2 \). \( \sigma_{\text {yielt }}=120 \mathrm{MPa}, \mathrm{E}=2.1 \times 10^{5} \mathrm{MPa} \) Tetmajer Equation for \( \lambda<\lambda_{\mathrm{p}}=105 \quad \sigma_{k}=310-1,14 \lambda \)
