$3.$ A bracket shown below has a solid circular cross section with a constant diameter of $60$ mm $.$ At the free end of the bracket a load of $\backslash (\backslash$mathrm$\{$P$\}1=4\backslash$mathrm$\{$kN$\}\backslash )$ acts in the $(-$z direction$)$ and a load of $\backslash (\backslash$mathrm$\{$P$\}2=3\backslash$mathrm$\{$kN$\}\backslash )$ acts in the $(-$y axis$).$ Calculate the resultant normal and shear stresses at point H $.$
