Can damping coefficient be negative
WebSep 20, 2024 · Can damping coefficient be negative? where the coefficients m, γ, and k were all positive. If γ is negative, the eigenvalues have positive real part and so the amplitude of the solutions increases exponentially. If γ2 < 4mk then the eigenvalues are complex and so the solutions have an oscillating component. Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators. Da…
