You are requested to use the software on the website for this problem. Take the same cross section as in Prob. $1($no ties are shown, but in a real design they would exist$).$

$($i$)$ Calculate the M$-$N interaction diagram for the section for both the $x-x$ and the $y-y$ axes for the material and bar area combinations shown. Normalize: $\frac{N}{f_{cd}}$ bh and $\frac{M}{f_{cd}}b{h}^2.$

$($ii$)$ Then plot the calculated $M-$ diagrams for all combinations.

$($iii$)$ Comment on your findings.
