4a- Explain what typical vibration problems you would expect to see monitoring a high frequency bandwidth of 2000Hz to 10000Hz, and what typical problems you can expect to see with a low frequency bandwidth of 2Hz to 1000Hz. 4b-Lack of lubrication within rolling element bearings can result in excessive metal-to-metal contact. How would you determine this was occurring using vibration analysis—provide spectra to illustrate your answer? What role does high frequency filtering techniques like amplitude demodulation play in analysing a lack of lubrication situation?
