# Carry over factor in beam calculation -- confusion

1. The problem statement, all variables and given/known data

I have several question regrading with this post .
1.) For BC and CB , we could see that it's far end pinned / roller supported , so , shouldnt be the K = (3/4)(EI / L ) ?
2.) I dont understand how the carry over factor works (in the second picture)

2. Relevant equations

3. The attempt at a solution
1.) I think the K for BC and CB are wrong , it should be K = (3/4)(EI / L ) ,, because at BA, we could see that K = (3/4)(EI / L ) ...

2.) I dont understand for the carry over factor for BA is 0 ... We can see that for AB , BC and also CD , the carry over factor is 0.5 , so shoulnt the carry over factor for BA is 0.5 also ?

I'm going to guess that you are not getting much response here, at least in part, to the use of the term "carry over factor." This is a strange term to me, and I've been doing things like this for a very long time. Can you re-word you question to convey your meaning more clearly?

The perhaps you can ask the person who drew up the syllabus what it means.
