Question

The figure shows a mechanical device in which force (s) are applied parallel to and away from the axis of the main, beam-like part. The device is supported by bearings at the locations marked with an X, which can provide reaction forces in any direction perpendicular to the axis of the beam. One of the bearings has the capability of resisting horizontally directed forces
1. Break the compound beam into parts consisting of each of the straight components.
2. Show the complete free body diagram of each component part including all external loads and internal forces and bending moments required to keep the part in equilibrium.
3. For the main, horizontal part only, draw the complete shearing force and bending moment diagrams.

Answer 1

this type of problems can be solved by just shifting loads by suitable load and moment analysis
