Problem $2(30$ points$)$

A$)$ The truss is supported by a roller at A and pin joint at H $.$ Assume the system is in equilibrium. On the figure to the right mark the following:

Any$/$all zero$-$force members with an $"$X$"$ on the figure to the right

Any$/$all two$-$force members with an $""$ on the figure to the right

Any$/$all multi$-$force members with an $"O"$ on the figure to the right

B$)$ Solve for the forces in members $AC,BE,BW,CW.$ Be sure to include any$/$all relevant FBDs $($there is more space for work on the previous page if needed$)$
