Show me the steps to solve Consider the beam shown in $($Figure $1).$ Assume that the rocker

provides reaction forces that are directed either outward or toward the

supporting surface perpendicular to the surface. Solve this problem

using the basic method. Follow the sign convention.

Figure

Draw the influence line for the vertical reaction at $A.$ Indicate the values of the influence line at each marked point along the beam.

Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines.

Note $-$ Draw discontinuity lines at each marked point along the beam.
