Viscous damping is added to an initially undamped spring-mass system. For what value of the damping ratio $\zeta$ will the damped natural frequency $\omega_{d}$ be equal to 90 percent of the natural frequency of the original undamped system?
A viscously damped spring-mass system is excited by a harmonic force of constant amplitude $F_{0}$ but varying frequency $\omega .$ If the amplitude of the steadystate motion is observed to decrease by a factor of 8 as the frequency ratio $\omega / \omega_{n}$ is varied from 1 to 2 determine the damping ratio $\zeta$ of the system.
Consider a system with a damping force undergoing forced oscillations at an angular frequency $\omega$. (a) What is the instantaneous kinetic energy of the system? (b) What is the instantaneous potential energy of the system? (c) What is the ratio of the average kinetic energy to the average potential energy? Express the answer in terms of the ratio $\omega / \omega_{0} .$ (d) For what value(s) of $\omega$ are the average kinetic energy and the average potential energy equal? What is the total energy of the system under these conditions? (e) How does the total energy of the system vary with time for an arbitrary value of $\omega$ ? For what value(s) of $\omega$ is the total energy constant in time?
