3.44 The landing gear of an airplane can be idealized as the spring-mass-damper system shown in Fig. 3.52 [3.16]. If the runway surface is described y(t) = y cos wt, determine the values of k and c that limit the amplitude of vibration of the airplane (x) to 0.1 m. y = 0.2 m, and @ = 157.08 rad/s . Assume m = 2000 kg, YOON y(t) x(t) (a) 00000 m (b) Wheel Runway Housing with strut and viscous damping Mass of aircraft, m 0
