A machine with mass M1 = 450 kg is mounted on 8 springs as shown. Each of these springs has stiffness = 70,000 N/m. If the floor's oscillation amplitude is constant at 0.01 m and the maximum allowable machine oscillation amplitude is 0.015 m, determine (a) the floor oscillation frequency (Hz) range allowed. (b) If the floor oscillation frequency is 5 Hz, find the # of springs required to isolate the machine to the required oscillation amplitude limit. Note: It is preferred not to change the mass of the machine, and you can assume the damping factor is constant at <= 0.1 Machine Floor 8 Springs in total
