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 \( n=2 \). \[ \sigma_{\text {yus }}=120 \mathrm{MPa}, \mathrm{E}=2.1 \times 10^{5} \mathrm{MPa} \] Tetmajer Equation for \( \lambda<\lambda_{p}=105 \quad \sigma_{k}=310-1,14 \lambda \)
