Question

A quantity that describes this phenomenon is expressed as a linear combination of two matrices denoted M and K in a numerical model named for Rayleigh. Multiplying the strength of this phenomenon by the factor “1 minus x squared” creates a system whose behavior is described by Lienard's theorem. (15[1])The strength of this phenomenon can be quantified by the logarithmic decrement. (15[1]-5[1])This phenomenon corresponds to the B term of the differential equation (15[1]-5[1])0 (15[1])equals (*) A times x double (10[1])prime, (10[1])plus B times x prime, (10[2]-5[1])plus (10[1])C times (10[1])x. (10[4])“Over” examples of this phenomenon (10[2])display no overshooting, (10[2])while “critical” (10[1])examples (10[1])have a Q-factor (10[1])of (10[1])one-half and minimize the time to static equilibrium. (10[1])For 10 points, name this phenomenon in which an oscillating system (10[1])loses energy and stops oscillating. ■END■

ANSWER: damping [accept damped; accept Rayleigh damping; prompt on energy loss or energy dissipation] (The second sentence refers to the van der Pol oscillator.)
