For the following problems, use the method of sections to find the member forces in chords indicated. In doing so$,$ provide the following:

Free body diagram for the truss as a whole showing the section cut drawn on the truss

Free body diagram of the section you choose to analyze

Member forces clearly indicating if they are tension or compression in your calculations

Note: you do not need to provide a summary diagram for this problem.

Question $5$:
