Shine down a light on me and show a path
I promise you I will return if you take me back.

I’m having trouble deciding if #1 is a mult-DOF system. Is the problem statement giving us the displacement of the end of spring 2 as esin(wt) relative to inertial space? aka that being what we would use to describe the stretch of spring 2? I tried the problem using x,y,z, and theta assuming esin(wt) to be a non-conservative force going into Qi, but I’m unsure of what to do with the Lagrangian at this point. The difficulty there made me question if I wasn’t supposed to use esin(wt) as the displacement and not even have to use the Lagrange equations at all.

Heading out for a beer now...

For question 3, is the isolator supposed to dampen?
