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

Add discontinuity lines and select segments to add to the canvas. Consider the beam shown in $($Figure $1).$ Follow the sign

convention.

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.
