Problem $7\mathrm{.}77$

Draw the moment diagram And shear for the beam. Follow the sign convention.

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.

Part B

Consider the beam in $($Eigure $1).$

Draw the moment diagram for the beam. Follow the sign convention.

Click on "add vertical line off" to add discontinulty 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.
