Assume that the life of a roller bearing follows a Weibull distribution with parameters 3 = 2.3 and o = 10,000 hours. (a) Determine the probability that a bearing lasts at least 8,000 hours. (Round your answer to 4 decimal places.) (b) If 10 bearings are in use and failures occur independently, what is the probability that all 10 bearings last at least 8,000 hours? (Round your answer to 4 decimal places.) (c) If ß = 2, determine the mean time until failure of a bearing. (Round your answer to 1 decimal place.)

A digital meter is used to determine the torque of a rotating shaft using single toothed flanges and inductive pick-ups. Static calibration show that the flange twist by an angle of one degree for an applied torque of 1000 Nm. In a test with the shaft rotating at 500 r.p.m., the torque calculated from the timer readings is 1200 Nm.
