Conjugate beam: help with clarification of given diagram, not with my work

  1. Dec 4, 2011 #1
    1. The problem statement, all variables and given/known data
    See problem number 2 as attached.

    3. The attempt at a solution

    I found the reactions and shear and moment diagrams for the original beam. I also drew the conjugate beam and loaded it with M/EI.

    My only question for this problem is what the 4EI and EI under the beam in the diagram mean. Presumably, the problem is implying that that there are two different materials. Do I just load the first segment with M/4EI?

    Thank you.

    Also, I assume that "under the concentrated load" means at point c, right?
