Okay, how would you set up the equation of motion then? I figured since there are two springs, one with damping and one without, it would be of interest to know the displacement in the node between the two springs. It would also be intereseting to find the displacement of the mass. That would...

I tried doing that but then the eig function in MATLAB will not solve the eigen values and the eigenvectors. I also checked with one of the teachers, he did not seem to think that was the right way to go.

Okay, I will repost this under the homework section! Thank you!

Hello! I am taking a course in dynamics and have a question about a spring-mass-damper system (see the attached file) that I want to solve using Lagrange equation (see attached file). I am having trouble writing the equation of motion for this problem. At first I tried doing it the way I...
