Question

Use MATLAB to plot the Bode diagram for the 1-DOF mechanical system in Problem 9.11 (Fig. P9.11).Estimate the frequency response for the position input xin(r) = 0.04 sin 50r m

by reading the Bode diagram(indicate the frequency response parameters on the plot of the Bode diagram). Obtain a more accurate answer by using MATLAB's bode command with left-hand-side arguments for computing magnitude and phase angle.
