Unformatted text preview: d) Evaluate the damping ratio. Based on the readability of the chart, which method would you pick? Log decrement or %OS? Why? e) Evaluate the natural frequency. f) Write down the frequency response function for this system, and the corresponding differential equation. ME 365 HOMEWORK 7 Fall 2011 Out: October 13, 2o11 Due: October 20, 2011 Problem 3: Given: Consider the frequency response plots shown below. Figures (iii) and (iv) are magnified views of Figures (i) and (ii), respectively, plotted on linear axes. To Find: (a) Determine the static sensitivity, K. (b) Determine the natural frequency of this system, ω n . (c) Use all three methods described in the notes to determine the system’s damping ratio. Compare your results....
