Part A

Consider the frame shown in $($Figure $1).$ The members are fixed connected at the supports and joints. $EI$ is the same for each member. Suppose that $w=4\frac{k}{f}t.$ In the calculation of moments using the moment distribution method, make $5$ steps that consist of carrying the moments over the spans and distributing them at the joints $($CO Dist.$),$ apply the method to all joints at the same time.

Part A

Determine the moment $M_{AB}$ acting on span $AB$ at A measured clockwise.

Express your answer using three significant figures. Enter positive value if the moment is clockwise and negative value if the mo counterclockwise.

Part B

Determine the moment $M_{BA}$ acting on span $AB$ at $B$ measured clockwise.

Express your answer using three significant figures. Enter positive value if the moment is clockwise and negative value if the mome counterclockwise.
