Problem $3\mathrm{.}86$: Amplitude of Rotating Unbalance A rotating machine of mass $M=100kg$ is supported on elastic mount, having stiffness of $k=50,000\frac{N}{m}$ and damping constant of $c=500N-s\frac{ec}{m}.$ The machine rotates at a speed of $6,000rpm$ and has eccentric mass $m=0\mathrm{.}005kg$ located at a distance of $e=0\mathrm{.}1m$ from the axis of rotation. Determine the amplitude of vibration of the machine.
