A steel hollow structural section $($HSS$)$ flexural member is subjected to a load of P$=22$ kips as shown. The cross$-$sectional

dimensions of the shape as also shown are d$=13\mathrm{.}25$in$.,$b$=10\mathrm{.}00$in$.,$ t$=0\mathrm{.}40$in$.,$ x$\_($H$)=4\mathrm{.}50$in$.,$ and x$\_($K$)=3\mathrm{.}25$in$.$ Using a$=16\mathrm{.}00$in$.,$

determine the principal stresses and the maximum shear stress acting at points H and K$,$ as shown. Show these stresses on an

appropriate sketch for each point.
