$2.$ A thin$-$walled pipe with an inner diameter of $24$ mm and a wall thickness of $1$ mm is subjected to an axial tensile force of $\backslash (1$ X $\backslash$mathbf$\{$k N$\}\backslash ),$ a torsional moment of $\backslash (2\backslash$times $\backslash$mathbf$\{$k N m$\}\backslash ),$ and an internal pressure of $\backslash (3\backslash$mathbf$\{$X$\}\backslash )$ Bar. The yield strength of the pipe material is $\backslash (\backslash$mathbf$\{400\}\backslash$mathbf$\{$~ M P a$\}\backslash ).$ Calculate the factor of safety of the thin$-$walled pipe according to the TRESCA criterion $($maximum shear stress theory$).$

Note: Replace $\backslash (\backslash$mathbf$\{$X$\}\backslash )$ with the last digit of your student number.
