In this section, we're going to examine harmonic excitation of SDoF systems. The last section was all about understanding the inherent characteristics of the spring-mass-damper model.

This section is about understanding what happens when we introduce an external dynamic force to that system. In particular we're going to focus on harmonic excitation. We'll discuss why harmonic excitation is such a key phenomenon to understand and its broader relevance in dynamic analysis.

We'll develop our understanding of transient and steady-state behaviour. Then we'll go on to characterise the steady-state behaviour and introduce the ideas of dynamic magnification factor and resonance.

We're going to finish this section with an in-depth example that will demonstrate exactly how to implement everything you've learned in the course so far.

When you complete this section you will have a good understanding of how to handle harmonic excitation. This is a key milestone in your journey to master structural dynamics!
