Consider the beam shown in $($Figure $1).$ Assume the supports at B

and C are rollers and A and D are pins. EI is constant.

Part A

Determine the moment M$\_($BA$)$ acting on span AB at B measured clockwise.

Express your answer to three significant figures and include the appropriate units. Enter positive value if the moment is clockwise and negative value if

the moment is counterclockwise.

M$\_($BA$)=$

Part B

Determine the moment M$\_($BC$)$ acting on span BC at B measured clockwise.

Express your answer to three significant figures and include the appropriate units. Enter positive value if the moment is clockwise and negative value if

the moment is counterclockwise.

$\backslash ]$ Draw the moment diagram for the beam. Follow the sign convention.

Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note $1-$ Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong.

Note $2-$ You should not draw an "extra" vertical line at the point where the curve passes the x$-$axis.

Note $3-$ Draw a vertical line to denote local maximum or minimum.

Note $4-$ The curve you choose from the drop$-$down is only a pictorial representation of a real quadratic$/$cubic curve. The equation of this curve is not mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the x$-$axis $($if any$)$ are not accurate.
