Develop the moment diagram for the frame below using the force method to solve for thereaction forces. Sketch the deflected shape. All members of the frame have the same flexural rigidity $(EI).$ Use the moment at $A$ as the redundancy.Here is a partial solution for the rotation and rotational flexibility at A that you can use to check your work with Castigliano's method: you should calculate that ${}_A=\frac{-6625}{EI}k**$

$f{t}^3(ccw)$ and ${}_{AA}=\frac{55}{3EI}f{t}^3(ccw)$

$3\frac{k}{f}t$
