A flange bolt wears out because of fatigue in accordance to lognormal distribution with MTTF = 10.00 hr and s =2.00. If preventive maintainance consists of periodically replacing the bolt, what is the reliability at 550hr with and without preventive maintance? Assume the bolts are replaced every 100 operating hours.
