Question $2$

The truss is pin$-$supported at A and rollersupported at $E,$ with forces applied at joints $C,D$ and $G.$ The dimensions are given in the figure.

$2\mathrm{.}1$ Use the method of sections with one sectional cut to calculate the forces in members $BC,GC$ and $GH$ and state if the members are tension$/$compression$/$neither$.$

$2\mathrm{.}2$ Calculate the forces in members $AB$ and $BG$ and state if the members are in tension$/$compression$/$neither$.$
