The cross section of a steel beam is constructed of a W 18 × 71 wide-flange section with a 6 in.

Hey everyone. So for this one, we need to get the channel. For this part, we have Y1 is equals t

Question

The cross section of a steel beam is constructed of a $\mathrm{W} 18 \times 71$ wide-flange section with a 6 in. $\times 1 / 2$ in. cover plate welded to the top flange and a $C 10 \times 30$ channel section welded to the bottom flange. This beam is subjected to a bending moment $M$ having its vector at an angle $\theta$ to the $z$ axis (see figure). Determine the orientation of the neutral axis and calculate the maximum tensile stress $\sigma_{\mathrm{t}}$ and maximum compressive stress $\sigma_{\mathrm{c}}$ in the beam. Assume that $\theta=30^{\circ}$ and $M=75$ kip-in. Note: The cross-sectional properties of this beam were computed in Examples D-2 and D-5.
