A ship's diesel engine causes resonance on the supporting foundation of the engine when its rotational speed reaches 900RPM. As the diesel engine increases its rotational speed to 1750RPM, the supporting foundation is seen to oscillate with an amplitude of 8mm. To decrease the amplitude of oscillation of the supporting foundation while at 1750RPM, the chief engineer decreased the foundation's stiffness by a factor of two. What is the resulting amplitude of oscillation?
