Q$2(50$ mark$)$:

Consider the frame shown in Fic$(2).$ The clobal axial displacement and rotation for the joint A are $13\mathrm{.}625mm$ and $(-0\mathrm{.}001\mathrm{.}489)$ radian respectively.

Impiemient the st iffricis method to tind

$($a$)$ The reactions at A and $D$ considering that node $C$ is equidistant to nodes $0$ and $B.$

$($b$)$ Draw the bchding moment diagarn for the frame.

mint the axial diplacement in joint A equal the axal doplacement in joint $B.$
