thread384-165178: vibration levels with spring isolators
How do we hand calculate the static load distribution (with known mass, inertia & CG) at each mount (know stiffness and locations relevant to CG) support manually for a 4 mount support system? Static indeterminate for more than 3 supports and force & moment balance does not help!
I was interested to have static deflection closer at each mount location.
Thanks in advance

RE: Load distribution
That should allow you to write enough independent equations to solve it.
What you have done is to invoke geometric compatibility as an additional constraint, I can't remember what the structures boys call it, but that is how you solve simple redundant systems.
