Space Elevator Safety - Vibrational Harmonics
... musical instruments, the cable of a space elevator has a natural resonant frequency ... If the cable is excited at this frequency, for example by the travel of elevators up and down it, the vibrational energy could build up to dangerous ... within the cable, and by scheduling travel up and down the cable keeping its resonant frequency in mind ...
LC Circuit - History
... an inductance should be oscillatory, and derived its resonant frequency ... a large battery of Leyden jars through a long wire, created a tuned circuit with its resonant frequency in the audio range, which produced a musical ... In 1857, German physicist Berend Wilhelm Feddersen photographed the spark produced by a resonant Leyden jar circuit in a rotating mirror, providing visible evidence ...
Minnaert Resonance
... resonance is the acoustic resonance frequency of a single bubble in an infinite domain of water (neglecting the effects of surface tension and viscous attenuation) ... The resonant frequency is given by where is the radius of the bubble, is the polytropic coefficient, is the ambient pressure, and is the density of water ... This formula can also be used to find the resonant frequency of a bubble cloud with as the radius of the cloud and the difference between the density of water and the bulk ...
Ceramic Capacitor - Electrical Characteristics - HF Use, Inductance (ESL) and Self-resonant Frequency
... For any discrete capacitor, there is a frequency above DC at which it ceases to behave as a pure capacitance ... This frequency where XC is as high as XL is called the self-resonant frequency ... The self-resonant frequency is the lowest frequency at which the impedance passes through a minimum ...

Famous quotes containing the words frequency and/or resonant:

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)

    Charity is a cop-out so traditionally female in its apparent self-effacement that there seems resonant comfort in it. We’re no longer supposed to serve the imaginations of men who have dominated us. We are to give up ourselves instead to those whose suffering is greater than our own. Looking down is just as distorting as looking up and as dangerous in perpetuating hierarchies.
    Jane Rule (b. 1931)
