Question

A machine, weighing 3000 N, is supported on a resilient foundation. The static deflection of
the foundation due to the weight is 7.5 cm. It is observed that the machine vibrates with an
amplitude of 1 cm when the base of the foundation is subject to harmonic oscillation at the
undamped natural frequency of the system with an amplitude of 0.25 cm. Find
(a) the damping constant of the foundation;
(b) the maximum force transmitted to the base;
(c) the amplitude of the displacement of the machine relative to the base.
