Chords and Collectors $($Drag Struts$)$

Part A: Given the lateral framing plan and loading scenario shown below and the corresponding free$-$body diagram, determine the active chord forces. $($HINT: Recall that the maximum bending moment in a cantilever beam is equal to the moment reaction at the support.$)(5000$ lb$)$

PART B: If the same $100$ plf wind blows in the other direction $($left$/$right$),$ and the diaphragm capacity is $100$ plf$,$ are drag struts required? Yes or No $($NOTE: All work is required. Assume the columns are equally spaced.$)(40$ plf$)$
