5. Consider modeling the vertical suspension system of a small sports car as a single degree of freedom system of the form: mx + cx + kx = 0 where m is the mass of the car and c and k are the equivalent damping and stiffness of the four-shock-absorber-spring systems. The car deflects the suspension system 0.05 m under its own weight. The suspension is designed to have a damping ratio of 0.3. a) Calculate the suspension system's equivalent damping and stiffness coefficients, if the car has a mass of 1500 kg. Also, determine the natural frequency. b) Then, with the same suspension, if two passengers, a full gas tank, and luggage totaling 350 kg are loaded in the car, determine the natural frequency and damping ratio. c) Comparatively discuss the results provided in parts (a) and (b) in terms of damping capacity, natural frequency, the amplitude of vibration, and time duration for vibration to nearly stop.

2. Figure 2 shows a simplified model to simulate a recording head flying over a rough disk surface in computer hard disk drives. The head has mass m and is supported by a suspension with stiffness k₁. Moreover, the moving disk surface will generate an air bearing lifting the head slightly above the disk surface (e.g., in the order of 20 nm). The air bearing is simplied as a linear spring with stiffness k2 and damping coefficient c. Let x(t) be the roughness of the disk surface and serve as the input excitation to the head/suspension system. Moreover, y(t) is the relative displacement of the head to the disk. In real hard disk drive applications, we want to keep y(t) almost constant, so that the head can follow the disk surface to perform read/write operations.

2. Figure 2 shows a roller rolling and slipping at the same time on a slippery surface. The center of the roller moves with a displacement r(t) and the roller rotates with angle (t). The roller has mass m, mass moment of inertia I, and radius r. In addition, a layer of fluid with viscous damping coefficient c is present to lubricate the roller. Moreover, the roller is pulled by a spring under a given (i.e., prescribed) displacement u(t), whereas the spring has spring constant k. Also, the roller is subjected to an applied torque M(t). Figure 3 shows the free-body diagram of the roller. Answer the following questions. (a) Apply F = ma to derive an equation of motion governing the translation z(t). (b) Apply M = Ia to derive an equation of motion governing the rotation 0(t). (c) Eliminate the variable (t) from the two equations of motion derived in parts (a) and (b). You should obtain a third-order differential equation in x(t). (d) Initially (i.e., at t = 0), the roller has no…
