1) As shown in the Figure 1, the system consists of rigid body AOJ pivoted at O supported by two springs (k, k) and two dampers (, C) located on two uniform discs. The system is also loaded with two concentrated masses (m, m). By using MATLAB script, determine and solve the following problems. a. The natural frequency of the system, wn- b.
