Damped Torsion Harmonic Oscillator

A torsion harmonic oscillator is a twisting system that, when displaced from its equilibrium position, experiences a restoring force proportional to the displacement. A damped torsion harmonic oscillator experiences a frictional force (damping) proportional to the velocity.

The angular frequency for a damped driven harmonic oscillator equals the natural angular frequency times the square root of 1 minus the damping ratio squared, as well as 2\[Pi] times the frequency. The frequency equals the reciprocal of the period. The natural frequency equals the square root of the torsional constant divided by the moment of inertia.

Formula

{QuantityVariable["ω", "AngularFrequency"] == Sqrt[1 - QuantityVariable["ζ", "Unitless"]^2]*QuantityVariable[Subscript["ω", "0"], "AngularFrequency"], QuantityVariable[Subscript["ω", "0"], "AngularFrequency"] == Sqrt[QuantityVariable["κ", "TorsionalConstant"]/QuantityVariable["I", "MomentOfInertia"]], QuantityVariable["ω", "AngularFrequency"] == 2*Pi*QuantityVariable["f", "Frequency"], QuantityVariable["f", "Frequency"] == QuantityVariable["T", "Period"]^(-1)}
