Back to the twomass system in figure 1 where mi 1 Kg m2 1

Back to the two-mass system in figure 1, where mi = 1 Kg, m_2 = 1 Kg, k_1 = 1 N/m, k_2 = 4 N/m, and C_2 = 8 Ns/m. Generate a squareroot locus plot (where damping element c_1 is the variable) Identify the acceptable range for c_1 such that the overall system is stable Design l select the appropriate damper constant ci necessary to achieve a dominant squareroot having a damping ratio of = 0.707 Plot the system response, x_1(t) and X_2(t), assuming a unit step response for the above design selection of C_1 Design/select the appropriate damper constant c_1 necessary to achieve a dominant squareroot that is real and has a time constant r = 4
