QUESTION 3 Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system, during normal system operation. One of the big problems of asset failure is the random failure which is difficult to predict. Discuss the potential failure (P-F) curve and the Weibull distribution. Give graphic example of the P-F curves and explain each of the probability density function terms. [10] QUESTION 4 To formulate a maintenance strategy three key points must be determined nameh
