Consider the beam shown in $($Equre $1).EI$ is constant

Assume $B$ and $C$ are rollers and A and $D$ are pinned.

Assume $w=1\mathrm{.}8\frac{k}{f}t.$

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

Express your answer in kilopound$-$feet to three significant figures. Enter positive value if the moment is clockwise and negative value if the moment is counterclockwise.

Correct

Correct answer is shown. Your answer $50\mathrm{.}29$ k $.$ ft was either rounded differently or used a different number of significant fgures than required for this par.

Part B

Determine the moment $M_{DC}$ acting on span $BC$ at $B$ measured clockwise.

Express your answer in kilopound$-$feet to three significant figures. Enter positive value if the moment is clockwise and negative value if the moment is counterclockwise.

$M_{DC}=-50\mathrm{.}41$
