# Damping constant. watch

1. Taken from a PM:

"Do you know if it is possible to find the damping constant required for critical damping (in a spring mass system) given the mass and attenuation constant? I don't do M4 so I've had to wing the dampening in this computer program that I am making, I'm trying to show case critical and over damping but I have no what the constants would be!"

standard form is d2x/dt2 + k dx/dt +w2x = 0

i.e SHM with angular frequency w (omega)
subject to resistance proportional to speed

HEAVY
if k2 >4w2

LIGHT
if k2 <4w2

Perfect!

Perfect!
equality is critical

equality is critical
Yeah that's what I assumed. It works perfectly when I set
