A collection of eight tubes cut to the length for musical notes (from shortest to longest) C,B,A,G,F,E,D, and C with each note a unique color. There are also caps for each tube to change the end of the tube from an antinode to a node. A musical book is included which is color coded for each note.

Resonance Reeds

This shows the "teeth" that vibrate one at a time depending on the speed.
Catalog: 
3A60.50A
Location: 
Ba3
A brass disk spins very fast. As it slows down the shortest "tooth" vibrates. As it further slows the longer teeth vibrate one at a time. A resonance, or vibrating-reed, tachometer uses a series of consecutively tuned reeds to determine engine speed by indicating the vibration frequency of the machine.

Torsion pendulum: moment of inertia on the period

The inertia of many shapes can be determined on the torsion pendulum.
Catalog: 
3A10.30A
Location: 
Ac6
Various combinations of masses and moments of inertia can be placed on the platform to study the effect of changing the moment of inertia on the period of rotational SHM. This one is adequate for quantitative measurements.
