Part E

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.

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 s 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 cu mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the $x-$axis $($if any$)$ are not accu
