Of course, there will usually be some damping component active in the case of a driven spring as well. So we need to combine Acts II and III together to see how the damping and driving forces interact. The equation is just a my"+by' +ky == A sin(wt) combination of the two: (again, we'll stick to a sinusoidal driving force). If you use the substitutions we used earlier (for wo and ), you can find the phase angle to be ArcTan 25 ww ยท]. What does this tell you about the impact of w's relation to wo's will be? (In other words, what 2 -02 does it mean if w> Wo, etc.?) Check your mathematical conclusion against the simulation.
