Question

Large amplitude of vibration is experienced when an engine having mass (1500 + 2) kg operates at a speed of 1500 rpm. An absorber having stiffness k₂equal to 1500 N/m and mass m₂ is attached to the primary system to absorb the vibration. Find:

The magnitude of the mass of the absorber.
The natural frequencies of the system after the addition of the absorber.

The values of the stiffness k₂and mass m₂ of the absorber in order to have the natural frequencies of the two degrees of freedom system 15% away from the forcing frequency.
