Question:

A 50-kg instrument is supported by four springs, each of stiffness 7500 \(\mathrm{N} / \mathrm{m}\). If the instrument foundation undergoes harmonic motion given in meters by \(x_{B}=0.002 \cos 50 t\), determine the amplitude of the steadystate motion of the instrument. Damping is negligible.
