Question $1(20$ points$)$: Support Reactions and Bending Moments in a Combined Beam$/$Truss Structure.

Consider the combined multi$-$span beam$/$truss structure shown in Figure $1.$

Figure $1.$ Front elevation view of multi$-$span beam structure.

The cantilever is fully$-$fixed to the wall at Point A$.$ Points B$,$ D and E are hinges. Horizontal and vertical point loads $3P(kN)$ and $P(kN)$ are applied to the truss as shown in Figure $1.$

$[1$a$](2$ pts$).$ Compute the degree of indeterminacy for the articulated beam structure $($A$-$B$-$C$-$D$-$E$-$F$-$G$-$H$).$

$[1$b$](3$ pts$).$ Identify the zero$-$force members in the truss structure. You can simply mark them up on Figure $1.$

$[1$c$](4$ pts$).$ Compute the distribution of forces throughout the truss structure. Draw a diagram summarizing your results. Draw bending moment and shear force diagram
