I have this model: http://i.stack.imgur.com/rVfpU.jpg
What values do I have:
1) $D_M$
2) $D_L - D_R$
What I can't figure out, is how to calculate the $C$ position represented on this image.
I don't have $D_L$ and $D_R$ individually, just the difference of them.
If you could help with some reference on how I can calculate the $C$ position, I would be grateful.
Thanks in advance.
