Group 11 element Parkes process. These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver
Conductor gallop an elastic spring obeying Hooke's law. Within the discipline of Mechanical vibration, conductor gallop is categorized as a self-excited vibration because the forces which generate conductor gallop are generated by the motion itself. One of the early leaders in modern mechanical vibrations, J. P. Den Hartog, described conductor gallop in a chapter on self-excited vibrations in his text book "Mechanical Vibrations", copyrighted in 1956 and reprinted by Dover Publications, where he develops general stability criteria for conductor gallop but without a complete mathematical solution. However, conductor gallop analysis also relates to Civil engineering because the electric conductors are carried by
