vibrations, show all steps and solutions A large rotating machine causes the floor of a factory to oscillate sinusoidally. Apunch press is to be mounted on the same floor as shown in Figure. Thedisplacement of the floor at the point where the punch press is to be mounted ismeasured to be y(t) = 0.1 sin w₁t (cm). Using the base support model of thissection, calculate the maximum force transmitted to the punch press at resonanceif the press is mounted on a rubber fitting of stiffness k = 40000 N/m; damping,c = 900 N.s/m; and mass, m = 3000 kg.Excitation source:Rotating machinePunch pressFloorSupport: c, kBase motion y(t)
