Question 1/49
If the total part failure rate of a machine is 0.00055 failures per hour, what would be the mean time between failures (MTBF) in hours?
Correct Answer: A
The mean time between failures (MTBF) is the inverse of the failure rate. The failure rate is givenas 0.00055 failures per hour, so the MTBF is 1/0.00055 = 1,818.2 hours. This means that the average time the machine operates without failing is 1,818.2 hours.
