Consider the beam shown in $($Figure $1).$ Solve this problem using the M$$llerBreslau principle. Assume that the rocker provides reaction forces that are directed either outward or toward the supporting surface perpendicular to the surface.

Part C

Draw the influence line for the shear just to the left of the support 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 sl 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 plac visually because the lines overlap, but the system will mark it wrong.
