||W41 - Torsional Oscillator
||The simple harmonic oscillator is perhaps the most generally useful model system in all of physics, and TeachSpin's Torsional Oscillator is a great way to learn and teach all of its properties. This system is of a human scale in space and time, and offers complete control of the restoring force, the inertia, and the damping. It can also be driven by an arbitrary electrical waveform, and it generates an electrical position signal as output. All the standard properties of a damped, driven, simple-harmonic-oscillator can be studied in detail. The apparatus makes possible dozens of investigations, and dozens more optional projects.
-- See the parts, and chart the outputs, of the Oscillator
-- Hand-excite the oscillator, to see the damped waveform
-- See that same waveform in the 'phase plane', of position vs. velocity
-- Excite the oscillator with a waveform of chosen shape, amplitude, and frequency, and explore the effect of varying the damping.
