Answer:
A body of mass 50 kg is supported by an elastic structure of stiffness 10 kN/m. The motion of the body is controlled by a dashpot such that the amplitude of vibration decreases to one-tenth of its original value after two complete cycles of vibration. Determine (i) the damping force at 1m/s (ii) the natural frequency of vibration
