Results For The Unforced Oscillator

Two interesting regimes for the characteristics of the unforced oscillator are:

  • When μ = 0, i.e. there is no damping function, the equation becomes:
This is a form of the simple harmonic oscillator and there is always conservation of energy.
  • When μ > 0, the system will enter a limit cycle, where energy continues to be conserved. Near the origin x = dx/dt = 0 the system is unstable, and far from the origin the system is damped. If the system does not begin precisely within a limit cycle, energy will be lost or gained - and work will have been done.

Famous quotes containing the word results:

    Consider what you have in the smallest chosen library. A company of the wisest and wittiest men that could be picked out of all civil countries in a thousand years have set in best order the results of their learning and wisdom. The men themselves were hid and inaccessible, solitary, impatient of interruption, fenced by etiquette; but the thought which they did not uncover in their bosom friend is here written out in transparent words to us, the strangers of another age.
    Ralph Waldo Emerson (1803–1882)
