$(50$ pts$)$ A frame structure shown in the figure below is subjected to a uniformly distributed force on member

$AB$ and a point force in the midspan of $CE.$ Joint $A$ is a fix support, joints $C,D,$ and $E$ are pin supports. The

connection at joint $B$ is rigid. If $EI$ is constant for all members, $w_o=10\frac{k}{f}t,$ and $P=100k,$

calculate the reaction moment at the fix support A and internal moments at joints $B$ and $C$ using the Moment

Distribution Method.
