Part B

Determine the internal end moment $M_{BA}$ acting on span $AB$ at $B.$

Express your answer int$-$ilopound feet using three significant figures. Enter positive value if the moment is clockwise and negative value if the moment is counterclockwise.

$M_{BA}=|,k*ft|$

PLEASE SOLVE Mab $,$ Mba, Mbc$,$ Mcb$,$ and please draw the moment diagram of the beam.
