A compound beam (see figure) has an internal moment release just to the left of B and a shear release just to the right of C Reactions have been computed at A, C, and D and are shown in the figure. First, confirm the reaction expressions using statics; then plot shear (V) and moment (W) diagrams. Label all critical Fand M values and also the distance to points where either V and/or M are zero.

A compound beam (see figure) has an internal moment release just to the left of B and a shear release just to the right of C Reactions have been computed at A, C, and D and are shown in the figure.
First, confirm the reaction expressions using statics; then plot shear (V) and moment (W) diagrams. Label all critical Fand M values and also the distance to points where either V and/or M are zero.
To draw : All supports for the given beam ABC and a rod CD and along with it diagrams of axial force, shear and moment for AB with the distance points where any critical ordinates is zero.
Explanation of Solution
Given Information:
We have the compound beam with internal moment release just to the left of point B and a shear release just to the right of point C shown in below diagrams.
The compound beam has a shear and moment release as below:
Below is the figure representing the segment portion AB of beam.
In the same manner for segment BC,
At point C, taking a moment,
For the segment CD of the beam,
At point C, taking the moment,
Now let us consider point E which is a point at distance b from point B where shear force is zero and the shear-force diagram is as shown below:
