Fixed on the left, _________ is the beam, ! is the dampner, @ is the mass, and 3 is the spring. Never mind the periods.
I'm tryin gto find the effective k for it.

wow, ummmm, best i could tell you is that the beam and spring *might* be considered two springs in series because they see the same load, and you could add them accordingly. Not sure if that helps, but there it is.
And the I'm not sure about how to handle the damper.

hmmm I might not even need the k for the beam. The problem doesn't give the Young'* modulus of the beam. Hmm so I guess keffective is just teh given spring constant.. Now the damping @ l=1/2m......
I still think I'm missing something...
