An experimental package and its support structure are intended to be placed on board the International Space Station. The package and its support structure act as a spring-mass system with a force constant of 2.06 x 1106 N/m and a mass of 109 kg . A NASA requirement for any experimental package, so that the package is not damaged by shaking during launch from Earth's surface, is that resonance for forced oscillations not occur for any frequency below 35 Hz.
What is the natural vibrational frequency of this package and support structure? Also, what is the resonant frequency of this package and support structure?
