Differential Equations - Mechanical Vibrations

It's now time to take a look at an application of second order differential equations. We're going to take a look at mechanical vibrations. In particular we are going to look at a mass that is hanging from a spring. Vibrations can occur in pretty much all branches of engineering and so what we're going to be doing here can be...

1.1 Bad vibrations, good vibrations, and the role of analysis. Vibrations are oscillations in mechanical dynamic systems. Although any system can oscillate when it is forced to do so externally, the term “vibration” in mechanical engineering is often reserved for systems that can oscillate freely without applied forces.
