1. The problem statement, all variables and given/known data See attachment. 2. Relevant equations 3. The attempt at a solution I don't get the first equation. Why is it 2pALx on the left side? Aren't we finding the mass center of the second shorter body? So shouldn't it then be (5/2)pALx? On the right side, I know pAL(L/2) is the mass center of the orange part on the left, but where did pAL(5L/4) come from? It seems like the 5L/4 is the mass center of the deformed total body, so I'm confused then why it seems to add over it twice. Any clear explanation would be appreciated, I'm obviously very confused about this.
