Therefore, the damped and undamped description are often dropped when stating the natural frequency ( e . g . with 0.1 damping ratio, the damped natural frequency is only 1 % less than the undamped ).

The instrument died out with Hebenstreit's retirement, but the idea of allowing sympathetic resonance from undamped strings was adopted into mechanisms that would disengage the dampers in various ways on early keyboard instruments such as the clavichord, called " pantalon stops ".

For example, an undamped second order system such as the suspension system in an automobile ( mass-spring-damper ), from where damper has been removed and spring is ideal, i . e . no friction is there, will in theory oscillate forever once disturbed.

Circuits with topologies more complex than straightforward series or parallel ( some examples described later in the article ) have a driven resonance frequency that deviates from } } } }, and for those the undamped resonance frequency, damped resonance frequency and driven resonance frequency can all be different.

Accurate measurements on the behavior of a climbing rope during the entire fall can be explained if the undamped harmonic oscillator is complemented by a non-linear term up to the maximum impact force, and then, near the maximum force in the rope, internal friction in the rope is added that ensures the rapid relaxation of the rope to its rest position.

*ARMD TORSION ( Rotor Bearing Technology & Software, Inc . )-Commercial FEA-based software for performing damped and undamped torsional natural frequencies, mode shapes, steady-state and time-transient response of mechanical drive trains with inputs of various types of external excitation, synchronous motor start-up torque, compressor torques, and electrical system disturbances.

The general solution is a sum of a transient solution that depends on initial conditions, and a steady state that is independent of initial conditions and depends only on the driving amplitude \, \ ! F _ 0, driving frequency, \, \ ! \ omega, undamped angular frequency \, \ ! \ omega _ 0, and the damping ratio \, \ ! \ zeta.
