Example 1 – four different single DOF systems with harmonic excitation Find the steady state response of the systems shown in (a)-(d): a) applied harmonic force b) support motion – relative displacement c) support motion – absolute displacement d) rotating imbalance As an exercise, sketch the frequency response plots of the amplitude and phase on the axes provided on a subsequent page. As you sketch, compare and contrast the frequency response functions for these four systems.
