Q In determining the maintenance tactic$/$ strategy and interval of the tactic for a crankshaft in a compressor subsystem, we need to know how it fails, the hazard rate and MTBF for each failure mode and the consequence of the failure mode.

This is false because we only need to know the criticality of the crankshaft failure modes to determine the maintenance strategy$/$ tactic and associated interval.

This is false because it is more efficient and equally effective to use the maintenance tactic$/$strategy supplied by the Original Equipment Manufacturer of the compressor

This is true because the hazard rate and MTBF describe the failure behaviour and understanding the consequence enables you to use RCM or other appropriate decision tree for tactic selection for each failure mode

This is true because we need to understand the failure behaviour and Explain MTBF importance? o Other Weibull distribution uses? $/$stem
