In the structure shown below members ABC and BDE are assumed to be solid rigid members. Member BDE is supported by a roller at point $E,$ and is pinned to member ABC at point $B.$ Member ABC is pinned to the wall at point $A.$ Member ABC is a aluminum rod with a diameter of $1$ inch. For this structure:

A$.$ Draw a Free Body Diagram showing all support forces and loads.

B$.$ Determine the axial stress in member ABC both in section $AB$ and section $BC.$

C$.$ Determine the movement of point $C$ due to the two applied loads.

$E_{al}=10{10}^6$

Unless otherwise indicated, all joints and support points are assumed to be pinned or hinged joints.
