Draw the shear 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 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 $2-$ 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.

Part D

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 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 $2-$ 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.
