Consider the beam shown in $($Figure $1).$ Follow the sign convention

Revie

Draw the moment diagram for the beam.

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 onfy one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it wil appear correct visually because the lines overlap, but the system will mark it wrong.

Note $2-$ Draw a vertical line to denote local maximum or minimum.

Note $3-$ 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.
