Damping coefficient units

Therefore, the SI unit of damping factor is Ns/m .

1. Does damping coefficient have units?
2. What is the value of the damping coefficient?
3. What is K in damping?
4. What is damping ratio ζ?

Does damping coefficient have units?

In Imperial units, damper velocities are usually in inches/s and forces in lbf, so the natural unit of damping coefficient is the lbf s/inch, which is a practical size of unit. The lbf s/ft is also usable, but rarer, and reduces to slug/s, although rarely expressed in the latter form.

What is the value of the damping coefficient?

The numerical value of the damping coefficient is c_t = 0.01 N s/m is obtained. with a numerical value of c_t = 0.00126 N s/m.

What is K in damping?

m is mass, k is the spring constant, and c is the damping coefficient.

What is damping ratio ζ?

The damping ratio is a measure describing how rapidly the oscillations decay from one bounce to the next. The damping ratio is a system parameter, denoted by ζ (zeta), that can vary from undamped (ζ = 0), underdamped (ζ < 1) through critically damped (ζ = 1) to overdamped (ζ > 1).
