Consider the beam shown in $($Figure $1).\backslash ($ E I $\backslash )$ is constant. Assume the support at $\backslash ($ B $\backslash )$ is a roller and $\backslash ($ A $\backslash )$ and $\backslash ($ C $\backslash )$ are fixed.

Part E

Draw the moment diagram. Follow the sign convention given in Chapter $4$ in the textbook.

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 $2-$ You should not draw an "extra" discontinuity line at the point where the 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.
