Use the method of virtual work to find

$($a$)$ the horizontal and vertical deflections at A$,$

$($b$)$ the vertical deflection and slope at C$.$

Consider both axial and bending deformations.

Set E $=29103$ ksi. For girder ABC, the moment

of inertia is $2$I $=480$ in$4$ and the area is $10$ in$2.$ For

column BD$,$ I $=240$ in$4$ and A $=6$ in$2.$
