Part D

Draw the moment diagram. 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 $1-$ Draw a vertical line to denote local maximum or minimum.

Note $2-$ 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 $\backslash ($ x $\backslash )-$axis $($if any$)$ are not accurate.
