$2.$ Determine the shear flows in the three$-$cell box beam under the loadings shown below. All stringers have areas of $\backslash (1-\backslash$mathrm$\{$in$\}^\{2\}\backslash )$ and each cell is $\backslash (10-\backslash$mathrm$\{$in$\}\backslash$times $10-\backslash$mathrm$\{$in$\}\backslash ).$ The upper and lower skins all have thicknesses of $0\mathrm{.}08-$in and the vertical webs all have thicknesses of $\backslash (0\mathrm{.}1-\backslash$mathrm$\{$in$\}\backslash ).($Assume that the stringers carry all the bending loads.$)$ For the ease of comparing results, number your stringers clockwise starting at the top left stringer. Note: since this problem has three cells, you will have to find three $\backslash (\backslash$mathrm$\{$q$\}\_\{\backslash$mathrm$\{$o$\}\}\backslash )\text{'}$s$,$ one for each cell. Therefore, you'll need to write three equations: a sum of moments equation, plus two twist continuity equations. The latter come from recognizing that the twist angle of the left cell must be the same as that of the center cell, which must be the same as that of the right cell.
