Acompressor is designed with two significant failure modes. the first is due to wear of the thrust bearing described by an exponential distribution with the bearing mttf 9 years the second, which includes all other causes, is represented by a constant failure rate.05 failures per year. if the reliability of compressor is to be kept above 0.8 by periodically replacing the thrust bearing. calculate the time for the first and the second replacement of the thrust bering to meet the 0.8 reliability target requirement for the compressor.
