Unformatted text preview: no other information on the system characteristics. You are asked to identify the system characteristics as described below: a) h , hysteretic damping coefficient, using the Nyquist plot only and b) ω n , natural frequency c) η , loss factor d) k , stiffness coefficient e) m , mass In your solution, state your reasonings clearly and show your steps in a detailed and neat form. Correct use of the units is extremely important in this homework. Remark: As you should have already learned, plot you were asked to generate in Question 2 of HW4 was a simply the Nyquist plot of F o ×| α ( ω )| , using the frequency ratio, ω / ω n , as the independent parameter. Using any of the plots obtained in parts b-e in the previous question...
