The cantilever is affixed to the free end of a square cross-section piezoelectric (PZT) block, which is fixed at the other end. Draw the schematic of the lumped-parameter model of the cantilever-PZT system, obtain the mathematical model of this mechanical system, and derive the lumped mass and stiffness of the PZT knowing that la = 0.01 m (length of PZT block), a = 0.005 m (side length of PZT cross-section), EPZT = 55 GPa (Young’s modulus), ?PZT = 7500 kg/m3 (mass density). The piezoelectric material losses are represented by an equivalent viscous damping coefficient cPZT = 60 N-s/m.

A polymer rod is tested to determine its viscoelastic response. The rod’s cross-section is square with the side of 5mm. The rod’s length before loading is 500mm. A tensile force of 500N is applied to the rod and the rod’s length under load was measured as a function of time. Instantly after applying the load, the rod is stretched to 508mm. After 24 and 48 hour under load, the rod’s length was measured as 550mm and 570mm, respectively. The load...
