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

AI Thread Summary
The discussion centers on clarifying the meaning of "4EI" and "EI" in a conjugate beam diagram related to a homework problem. The user has successfully calculated the reactions and shear and moment diagrams but seeks confirmation on how to apply the loading for different materials indicated by the varying EI values. There is a specific inquiry about whether to load the first segment with M/4EI and if "under the concentrated load" refers to point c. The conversation emphasizes understanding the implications of material differences in the context of beam loading. Clear guidance on these points is necessary for accurate problem-solving.

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?
