Figure Q$3$ shows a short column which carries a single $10$ kN compressive load eccentric to both axes. The column is of Square hollow cross$-$section with external dimensions $\backslash (150\backslash$mathrm$\{$~mm$\}\backslash$times $150\backslash$mathrm$\{$~mm$\}\backslash )$ and with a wall thickness of $10$ mm $.$ Determine the value of the stress at the extreme fibres at the positions marked a$,\backslash (\backslash$mathrm$\{$b$\},\backslash$mathrm$\{$c$\}\backslash ),$ and d$.$
