A 135 lb washing machine is supported by four circular pads. Each pad has an elastic modulus of 600 psi, a height of 2.5 inches, and a diameter of 1.25 inches. The machine primarily vibrates side to side. Assume the damping ratio of the system is 0.12. A 15 lb (when wet) blanket is being washed. The blanket can be modeled as a point mass 15 inches from the center of rotation. Suppose the washing machine is spinning at 600 rpm. a) Find the amplitude of vibration. b) Find the amplitude of the force transmitted to the ground. c) Will the washing machine shake more or less if it spins faster?
