    Natural Frequency - Simultaneous Equations

    Hi,

    I'm trying to work out both K and M from the following two equations using simultaneous equations. Can anyone show me how?

    Wn = 3982.87 = k/m

    Wn = 2555.3 = k/m + 0.1

    Thanks in advance

    Actually this is lsightly more logical:

    63.11 = SqRT(k/m)

    50.55 = SqRT(k/m + 0.1)

    Can anyone help?
    Neither pairs of equations you've proposed have a consistent solution.
