An 8 kg instrument needs to be isolated from aircraft engine vibrations. Assume the engine vibrates at frequencies ranging from 1,400 to 2,600 RPM. Also assume the damping ratio is 0.05. a) What should the stiffness be so that the transmissibility is 5% or less over the entire operating range? b) Is this the minimum or maximum allowable stiffness?
