Any mechanical

Any mechanical component will unavoidably possess both mass and stiffness. This translates in electrical terms to an LC circuit, that is, a circuit consisting of an inductor and a capacitor, hence mechanical components are resonators and are often used as such. It is still possible to represent inductors and capacitors as individual lumped elements in a mechanical implementation by minimising (but never quite eliminating) the unwanted property. Capacitors may be made of thin, long rods, that is, the mass is minimised and the compliance is maximised. Inductors, on the other hand, may be made of short, wide pieces which maximise the mass in comparison to the compliance of the piece.[7]
Mechanical parts act as a transmission line for mechanical vibrations. If the wavelength is short in comparison to the part then a lumped element model as described above is no longer adequate and a distributed element model must be used instead. The mechanical distributed elements are entirely analogous to electrical distributed elements and the mechanical filter designer can utilise the techniques of electrical distributed element filter design.[7]

Foreign policy drove the Bush presidency; military operations were conducted in Panama and the Persian Gulf at a time of world change; the Berlin Wall fell in 1989 and the Soviet Union dissolved two years later. Domestically, Bush reneged on a 1988 campaign promise and after a struggle with Congress, signed an increase in taxes that Congress had passed. In the wake of economic concerns, he lost the 1992 presidential election to Democrat Bill Clinton.
