  2. Wilberforce pendulum - Wikipedia

    en.wikipedia.org/wiki/Wilberforce_pendulum

    A Wilberforce pendulum can be designed by approximately equating the frequency of harmonic oscillations of the spring-mass oscillator f T, which is dependent on the spring constant k of the spring and the mass m of the system, and the frequency of the rotating oscillator f R, which is dependent on the moment of inertia I and the torsional ...

  3. Elastic pendulum - Wikipedia

    en.wikipedia.org/wiki/Elastic_pendulum

    In physics and mathematics, in the area of dynamical systems, an elastic pendulum [1] [2] (also called spring pendulum [3] [4] or swinging spring) is a physical system where a piece of mass is connected to a spring so that the resulting motion contains elements of both a simple pendulum and a one-dimensional spring-mass system. [2]

  4. Effective mass (spring–mass system) - Wikipedia

    en.wikipedia.org/wiki/Effective_mass_(spring...

    The effective mass of the spring in a spring-mass system when using a heavy spring (non-ideal) of uniform linear density is of the mass of the spring and is independent of the direction of the spring-mass system (i.e., horizontal, vertical, and oblique systems all have the same effective mass). This is because external acceleration does not ...

  5. Natural frequency - Wikipedia

    en.wikipedia.org/wiki/Natural_frequency

    In a massspring system, with mass m and spring stiffness k, the natural angular frequency can be calculated as: = In an electrical network , ω is a natural angular frequency of a response function f ( t ) if the Laplace transform F ( s ) of f ( t ) includes the term Ke − st , where s = σ + ω i for a real σ , and K ≠ 0 is a constant ...

  6. Mechanical resonance - Wikipedia

    en.wikipedia.org/wiki/Mechanical_resonance

    The Taipei 101 building for instance relies on a 660-ton pendulum—a tuned mass damper—to modify the response at resonance. The structure is also designed to resonate at a frequency which does not typically occur. Buildings in seismic zones are often constructed to take into account the oscillating frequencies of expected ground motion.

  7. Resonator - Wikipedia

    en.wikipedia.org/wiki/Resonator

    A physical system can have as many resonant frequencies as it has degrees of freedom; each degree of freedom can vibrate as a harmonic oscillator.Systems with one degree of freedom, such as a mass on a spring, pendulums, balance wheels, and LC tuned circuits have one resonant frequency.

  8. Oscillation - Wikipedia

    en.wikipedia.org/wiki/Oscillation

    The simplest mechanical oscillating system is a weight attached to a linear spring subject to only weight and tension. Such a system may be approximated on an air table or ice surface. The system is in an equilibrium state when the spring is static.

  9. Rotational–vibrational coupling - Wikipedia

    en.wikipedia.org/wiki/Rotational–vibrational...

    This discussion applies the following simplifications: the spring itself is taken as being weightless, and the spring is taken as being a perfect spring; the restoring force increases in a linear way as the spring is stretched out. That is, the restoring force is exactly proportional to the distance from the center of rotation.
