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

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 - You should not draw an "extra" vertical line at the point where the shear curve passes the x-axis.

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. 

Part B

Draw the moment diagram for the beam.
