The figure illustrates a number of beam sections. Use an allowable bending stress of $11\mathrm{.}8k$ for steel and find the maximum safe uniformly distributed load that each beam can carry if the given lengths are between simple supports. NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Consider a simple support steel channel having a load of $6lb\frac{f}{f}t,$ thickness of $3-$in$,$ and length of $60$ inches. $($Refer to Table A$-7$ for values of moment of interia.$)$

The maximum safe uniformly distributed load is determined to be Ibf$/$in$.$
