|For β = 0.2 s–1, produce computer plots like those shown in Figure 3-15 for a sinusoidal driven, damped oscillator where xp(t), xc(t), and the sum x(t) are shown . Let k = 1kg/s2 and m = 1kg. Do this for values of w/w1 of 1/9, 1/3, 1.1,3, and 6. For the xc (t) solution (Equation 3.40), let the phase angle δ = 0 and the amplitude A = – 1m. For the xp (t) solution (Equation 3.60), let A = 1 m/s2 but calculate δ. What do you observe about the relative amplitudes of the two solutions as w increases? Why does this occur? For w/w1 = 6, A 20 m/s2 for xp (t) and produce the plot again.|
