Discrete Linear Systems

  • Giancarlo Genta


The simplest of the systems studied by structural dynamics is the linear mechanical oscillator with a single degree of freedom consisting of a point mass suspended by a linear spring and, possibly, a viscous damper (Figure 1-la). Historically, however, the mathematical pendulum (Figure 1-1c) represented for centuries the most common paradigm of an oscillator, which could be assumed to be linear, at least within adequate limitations.
