Yes. The thing is figuring out what b value I need for any drop between 25mm and 1200mm. At a height of 1000mm what b do I need to be critically damped? At a height of 400mm what b do I need to be critically damped? and so on. Vibration teacher says that the impact is making this problem...

Homework Statement vinit = sqrt(2g*h); h = drop distance vfinal = 0; xinit = 0; xfinal = 100mm; a = g; Issue: non-linear damping. M*x'' - b*(x')^2 - k*x = 0; b = 128*mu*(length fluid travels)*(D^4(piston)/[(D(hydraulic)^4)(orifice opening)]every book I've been reading on vibrations damping...
