A single degree of freedom mass-spring-viscous damper system

Home » Theory of Machines » Theory of Machines Miscellaneous » Question

A single degree of freedom mass-spring-viscous damper system with mass m, spring constant k and viscous damping coefficient q is critically damped. The correct relation among m, k, and q is

1. q = √2km
2. q = 2√km
3. q = √2k/m
4. q = 2√k/m

Correct Option: B

w_n =	q
	2m

q = 2mw_n = 2m √	k
	m

q = 2√km
