Free undamped vibrations

Whenever an object/system displaces in either side of its equilibrium position with the help of an external/internal means, then the object/system moves regularly or randomly on both sides of its equilibrium position. This motion is called vibration. Generally, there are three types of vibration: longitudinal vibration, transverse vibration, and torsional vibration.

Question

Q3:
A 2500-kg heavy engine has a high resonance at 140 Hz. The operation manager
utilizes an elastomer (engine mount) to an engine of weight 400 kg tuned to 140 Hz.
Determine the range of frequencies at which the amplitude of the engine vibration is
less with the mount installed than without the mount.
