Hey guys,

I have this questions that I need to solve. I have to shrink the massive block diagram down so that I end up with a close loop Transfer Function at the end.

I have shrunk it down a fair bit but I'm stuck at the moment..

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

2. Relevant equations

Jt = Jm+N*N*JL

Bt=Bm+N*N*BL

3. The attempt at a solution
This is what I have ended up with, after some moving around..

I'm mainly stuck on the Kt, Kb feedback loop...
