Consider the beam shown in $($Figure $1).$ Solve this problem using the basic method

Figure

Part A

Draw the influence line for the vertical reaction at $B$

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 influence line passes the $x-$axis.

Note $2-$ Be sure to indicate the correct types of the functions between the lines, e$.$g$.$ 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.

Note $3-$ Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place $2$ vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong.

Add discontinuity lines and select

segments to add to the canvas.

Please draw the influence line for shear just to the right lf the rocker at A$,$ and the influence line for the bending moment at C
