Q$3.$ The mechanical member shown in Figure $3$ is made of metal of $\backslash (\backslash$mathrm$\{$S$\}\_\{$y t$\}\backslash )$ of $150$ MPa and $\backslash (\backslash$mathrm$\{$S$\}\_\{\backslash$mathrm$\{$yc$\}\}\backslash )$ of $310$ MPa $.$ Draw the stress element at the locations A and B showing the all the stresses $($Stress state$)$ and calculate the value of the force $"\backslash (\backslash$mathrm$\{$F$\}^\{\backslash$prime$\}\backslash )$ based on the most suitable theory of failure.
