Consider the beam shown in $($Figure $1).$ The support at $B$ settles $0\mathrm{.}15$ ft $.E=29({10}^3)ksi$ and $I=7500$ in$.{?}^4$ Assume the supports at $B$ and $C$ are rollers and $A$ is fixed.

Part B

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

Part C

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

Part D

Determine the internal end moment $M_{BC}$ acting on span $BC$ at $B$ measured clockwise
