"Statics is fun ... except when your professor gives you a test question he didn't set up right and you end up with a rope in compression"
Statics was fun, but dynamics was a pain. There was some black chick in our dynamics class that was already working out at NASA and she made the rest us of us look stupid.
Anyway, a simple thought experiment would be:
If 100% of the force was on the front jacks, the CG would be directly over the front jacks.
If 100% of the force was on the rear jacks, the CG would be directly over the rear jacks.
If 50% of the force was on both the front jacks and rear jacks, the CG would be 50% between them.
