e consider the same single degree of freedom system we had earlier but subject it now to a force, F (t). Frequently in practice, the force is a complicated function of time, and we will loo

SDOF Systems: Free Damped Response
3.1 Introduction
hen we looked at a mass-spring system we noticed that the predicted response was a sinusoidal oscillation that lasted forever. This is of course patently untrue in that all real systems would s
