Consider the beam shown in $($Figure $1).$ Assume the support at $B$ is a pin. 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 $1-$ You should not draw an "extra" discontinuity line at the point where the shear curve passes the $x-$axis.

Note $2-$ The curve you choose from the drop$-$down is only a pictorial representation of a real quadraticlcubic 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.
