Resonant Characteristics of Rectangular Microcantilevers Vibrating Torsionally in Viscous Liquid Media [PDF]
, 2012 The resonant characteristics of rectangular microcantilevers vibrating in the torsional mode in viscous liquid media are investigated. The hydrodynamic load (torque per unit length) on the vibrating beam due to the liquid was first determined using a ...
