what I'm trying to say is that the bar is not an isolated torsion spring. to truly understand what's going on you need to write down two eqations:
Sum of all forces = 0
Sum of all torques = 0
and solve the system. I assure you, the result will be different. notice that two forces remain the same (see picture)
so much for general comments, I need a book on suspension to continue. unfortunately MSU is a big university and its cold outside, so I'm not going to engeneering building to get an appropriate book any time soon.
