For the truss shown, determine

a$)(8$ pts$)$ Any zero$-$force members through inspection only

b$)(25$ pts$)$ The forces in members AB$,$ AL$,$ CD$,$ DE$,$ DH$,$ DG$,$ EG$,$ and GH through the method of joints

c$)(12$ pts $)$ The forces in members BC$,$ BI$,$ and II through the method of sections$**$

You must solve for $BC,BI,$ and II with equations where each member is the only member in the equation $($for example, you cannot use BC in an equation that solves for Cl even if you know $BC-BI$ must be the only member in the equation$).$
