Crossmember forces

This question might seem odd, but I will ask any ways. How much force is on the lower control arm mount. By theory shouldnt the bulk of the load be asorbed by the bag or spring?

if you were looking at it as a design standpoint you would really place all of the theoretical weight on there, just to make sure it is over designed.  If that makes sense.  The bag and spring are simply displacing the force, not absorbing any energy

Makes sense, after reading over the post again I was over thinking it.
