Q Factor - Mechanical Systems

Mechanical Systems

For a single damped mass-spring system, the Q factor represents the effect of simplified viscous damping or drag, where the damping force or drag force is proportional to velocity. The formula for the Q factor is:

Q = \frac{\sqrt{M k}}{D}, \,

where M is the mass, k is the spring constant, and D is the damping coefficient, defined by the equation, where is the velocity.

Famous quotes containing the words mechanical and/or systems:

    “A man should have a farm or a mechanical craft for his culture. We must have a basis for our higher accomplishments, our delicate entertainments of poetry and philosophy, in the work of our hands.”
    —Ralph Waldo Emerson (1803–1882)

    “Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
    —Ralph Waldo Emerson (1803–1882)
