Question 4. Elizabeth Barton, the mad maid of Kent as a teller of divine proclamations. She became a nun and so was investigated first by the church to ensure she did not offend the teachings of the church. Eventually Elizabeth met Cardinal Wolsey (shown) and then the King. Her foretellings were popular with the king until he wanted an annulment from Catherine of Aragon. Apparently she considered it wise to warn the King he would die in the near future if he married Anne Boleyn. Elizabeth was hung soon after that prophecy. A fault tree is shown overleaf (next page) for the prophecy telling of the 14th century in UK. 4a) Draw the reliability block diagram corresponding to this tree. 4b) Find the Structure function. 4c) Given the hazard rates listed below, compute the Mean Time to Failure. 4d) Explain how you might construct a "success tree" from the fault tree. What is the value of a success tree? 4e) How is MTTF used to calculate the availability of a system? A = 1 x 10-5hr-1 = = 4 x 10-5hr-1 Ac = 2 x 10-5hr-1 AD = 3 x 10-5hr-1 A= = 5 x 10-5hr-1 Hazard rates for Question 4
