Problem #$5-$ Combined Stress Analysis $(15$ points, $4$ parts$)$

A W$14$x$61$ wide$-$flange section made of A$633$ structural steel is used as a simply supported beam with a span length of $14$ ft $.$ The beam is subjected to a uniformly distributed load of $18\mathrm{.}1$kip$\frac{s}{f}t($which includes the self$-$weight of the beam$)$ and an axial compressive force of $50$ kips $.$ Show all work and any assumptions clearly. Complete the following:

Part A $($s points$)$: rind me axia stress in me deam.

$()$

$()$

Part D $(5$ points$)$: Calculate the total combined stress at the top and bottom of the flange.
