Problem $7\mathrm{.}82$

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

Part B

Draw the moment diagram 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 $1-$ 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.

Draw the shear diagram 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 $1-$ 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.

Note $2-$ Be sure to indicate the correct types of the functions between the lines, e$.$g$.$ if in your answer the type of a function is "linear increasing slope" for

the function that actually has linear decreasing slope, the answer will be graded as incorrect. Use the button "change segment" if necessary.
