Components A and B are connected in parallel. A and B are then
connected in series with components C and D. The reliability values for A
and B are 0.90 and 0.95 respectively. The reliability values for C and D
are 0.90 and 0.99. What is the system reliability? Ans: .8865
Determine the failure rate for an item that has the test of 10 items
terminated at the end of 20 hours. Five of the items failed after 2, 4, 8,
10, and 11 hours respectively. Five items are still operating at the end of
22 hours. The items were not replaced. Ans: .037

continuously for 8000 hours or until failure. Of the 11 motors that were
tested, only 1 failed at 4270 hours. The remaining 10 motors were
operational throughout the experiment. When the motor failed it was not
replaced. Determine the failure rate. Ans: .0000119
