Problem #$26-$ Combined Stress Analysis $(10$ points, $4$ parts$)$

A W $2193$ wide$-$flange section made of high$-$strength low alloy $($HSLC$)$ structural steel is used as a simply supported beam with a span length of $18f.$ It is subjected to a uniformly distributed load of $14\mathrm{.}9$kip$\frac{s}{f}t.($which excludes its own weight$)$ and an axial compressive force of $276$kips. Compute the maximum tensile and compressive stresses at the top and bottom of the beam $($be sure to include the beam's self$-$weight when determining the maximum bending moment. Complete the following:

Part A $(2$ points$)$: Find the axial stress in the beam.

Part B $(2$ points$)$: Calculate the maximum bending moment in the beam.

Part C $(2$ points$)$: Calculate the bending stress in the beam.

Part D $(4$ points$)$: Calculate the total combined stress at the top and bottom of the flange.
