Draw the moment diagram for the beam.

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 - 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 x-axis
(if any) are not accurate.
Note 3-Be sure to indicate the correct types of the functions between the lines, e.g. in your answer the type of a function is "linear
increasing slope" for the function that actually has linear decreasing slope, the answer will be graded as incorrect. Use the button
"change segment" if necessary.
Note - 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 visually correct because the lines overlap, but the system will mark it wrong.
