Question $2$:

Four $44\frac{1}{2}$ angles are used to form the compression member shown in the accompanying illustration. The member is $35$ ft long, has pinned ends, and consists of A$50$ steel. Determine the LRFD design strength of the member. Design single lacing and end tie plates, assuming connections are made to the angles with $\frac{3}{4}-$in diameter bolts.

Hint: Check for the gage length, g$,$ from Table $3-1,$ to find the distance.

Please note that there is a typo the distance of the back of the $4$L$\text{'}$S was written in the ft units it is a typo and should be inches $($i$.$e$.,14$in$)$
