Question $2$ is based on Figure $2,$ For the simply supported truss shown involve a pinned support at A and a roller support at $B,$ all the vertical members are $3$ meters and all the horizontal members are $1\mathrm{.}5$ meters.

Figure $2.$ Truss diagram.

Question $2$a

Calculate the support reactions at A and $B.$

Question $2$b

Using the joint resolution, determine the forces in members $b$ and $c$ of the truss to one decimal place and state whether the members are in tension $(T)$ or compression $($C$).$ Show the free body diagrams of the joints clearly.

Question $2$c

Using the method of sections, determine the forces in member $e,f,g$ and state whether the members are in tension $(T)$ or compression $($C$).$ Show the free body diagrams of the joints clearly.
