Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

3. Draw complete, clearly labeled free-body diagrams. All unknown support reactions should be clearly labeled with a variable name. All known values such as weight or applied forces should be clearly labeled with their known values.

Don't need to show equilibrium equations, I just need free-body diagrams. Only solve this text question, not the questions in image.
