$1\mathrm{.}1$ The interns came up with two different truss systems to enclose the gallery during the design charette and have given you different design options. However, you somehow can't figure out how to draw them with graphic statics. Why is that $(2\mathrm{.}5$pt$)$ and which ones can you analyze $(2\mathrm{.}5$pt$).$ Hint: determine the degree of the internal statical determinacy for each truss.
