Q.4 (a) An electric motor of mass 50 kg is suspended from a support structure on a four-spring system. The springs are arranged in series, with the four stiffnesses being 15 kN/m, 25 kN/m, 30 kN/m and 40 kN/m respectively. Viscous damping is present within the system and the damping ratio is 0.175. i) Produce a neat sketch of the system and state its equation of motion. ii) Determine the level of the viscous damping in the system. iii) Determine the amplitude of vibration of the motor 10 cycles after it is released from an initial displacement of 125 mm.

2. Consider a car suspension, modeled as a mass/spring/damper system (mass m, stiffness k, damping b). Suppose the height of the chassis is lo at rest, the height of the terrain below the driver varies as h(t), and the height of the chassis is denoted lo + y(t). (i.e., spring deflection away from rest is y(t) – h(t)). 2 (a) Give the transfer function G(s) = H(s) · = (b) Suppose the ground follows an oscillatory profile h(t) A cos(wx (t)) with magnitude A (in meters) and frequency w (measured in radians per meter). Suppose the car is traveling at a constant forward speed v. Using a frequency response analysis strategy, give the amplitude of oscillations experienced by the driver at steady state as a function of m, k, b, A, w, and v. Hint: You can't simply consider |G(iw)| to get the amplification in this case. (c) Suppose the ground varies by A = 5cm, w = 2 rad/m, and you are driving at v = 15 m/s. Using your answer to part (b), what amplitude of oscillation is felt by the driver when m…
