Download scientific diagram | Three ''Euler disk'' systems investigated in this work: a) the Euler disk toy, b) a common cooking pot lid and c) a fan grill. While a) oscillations are measured with a microphone b) and c) oscillations are measured with a gyroscope. from publication: The Euler disk and its dynamic finite time singularity: Investigating a fascinating acoustical and mechanical phenomenon with simple means | Many have spun a coin or other disk on a table, observing — and listening! — that — while its motion comes to rest, the angular velocity of the contact point and the frequency of the emitted sound raise in a striking way. This dynamical system is known as the "Euler disk," | Mechanical Phenomena and Investigation | ResearchGate, the professional network for scientists.
