Question
Two beams (ABCD and DE) are connected using a pin at Point D. The pin acts as a moment release,
i.e. no moments are transferred through this pinned connection. Shear forces can be transferred
through the pinned connection at point D. Beam ABCD has a pinned support at point A and a roller
support at Point C. Beam DE has a roller support at Point E. A concentrated load, P, is applied to the
mid span of beam DE, as shown below. Another concentrated load, 2P, is applied to Point G. The
bracket BFG can be considered rigid.

Figure 1: Two beam arrangement for question 1.
To analyse this structure, you will:
a) Construct the free body diagrams for the structure shown above. When constructing your
FBD's you must make section cuts at point B, C and D. You do not need to construct the free
body diagram for bracket BFG. You can represent the structure as four separate beams.
Following this, construct the bending moment and shear force diagrams for each segment of
the beam. Do not substitute in values for P, L etc. Keep your answer in algebraic form.
