No Effect of Steady Rotation on Solid $^4$He in a Torsional Oscillator [PDF]
, 2015 We have measured the response of a torsional oscillator containing polycrystalline hcp solid $^{4}$He to applied steady rotation in an attempt to verify the observations of several other groups that were initially interpreted as evidence for macroscopic ...

Vibration Characteristics Analysis of a Piezoelectric Disc or Torsional Transducers [PDF]
Transactions of the Korean Society for Noise and Vibration Engineering, 2005 This paper presents an analytical approach for the vibration characteristics of a piezoelectric disc for torsional vibration transducers. The characteristic equation of the piezoelectric annular disc has been derived from Gibbs` free energy equations and mechanical and electrical equilibrium.
