Question: 1 oscillating system performs damped oscillations with frequency 1000 hz...

Question details

1. Oscillating system performs damped oscillations with frequency 1000 Hz. Determine the frequency of natural oscillations if the resonance frequency is 998 Hz. 2. Amplitude of vibrations during 5 minutes decreased by 2 times, during which time the amplitude reduced by 8 times? 3. For 8 minutes amplitude decreased 8 times. Find damping factor. 4. Determine how much resonance frequency is different from the natural oscillation 5. Find damping factor for oscillating system, if it is knowing that in the 10 s amplitude 6. The amplitude of oscillations is reduced by 10 s from 10 cm to 9 cm. Period of 7. During the 10 s amplitude decreased 3 times. How long it will decrease by 10 times? frequency (IkHz) when the damping factor is 400 sT. decreased 20 times. oscillation is 0.4 s. Find damping factor.
