Consider the beam shown in $($Figure $1).$ Assume the support at BB is a pin. Follow the sign convention. Part A

Consider the beam shown in $($Figure $1).$ Assume the support at $\backslash ($ B $\backslash )$ is a pin. Follow the sign convention.

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 $\backslash ($ x $\backslash )-$axis.

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 $\backslash ($ x $\backslash )-$axis $($if any$)$ are not accurate.

Figure Part B

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 $1-$ Draw a vertical line to denote local maximum or minimum. discontinuities and intercepts with the x$-$axis $($if any$)$ are not accurate.
