    No, and also your 4 support solution doesn't look right .
    Since my solution used the same assumptions, it is also wrong.
    I redid it for the 4 point and got
    P1=.24F,P2=.191F
    P3=.308F, P4=.260F...

    I think I have a somewhat rational method for getting the forces.

    Using your idea of distributing the loads along the 2 axes (P1-P2, P3-P4 for the problem of further distributing that force must...

    My 2 cents.

    Neither method proposed is accurate since they do not both satisfy the 3 static equilibrium equations.

    If you have n mounts on a spring mounted system with an inflexible mounting...

    This is also true for beams and answers the OP question (BTW what happened to him/her?)

    Wongw,

    Could you show a sketch of the load mass(es) and and the nature of the driving vibration so that we
    can understand the application. I suspect that you are assuming an inflexible beam...
