For a machine component, the time to failure was found to be lognormal with s= 1.3. There is a requirement that the reliability needs to be 0.95 for 700 hours. a. Determine the median time to failure that must be achieved. 22ht74563-820 23/05/21-202231 b. Find the corresponding MTTF. c. Find the corresponding standard deviation. d. If the desired MTTF is obtained, what is reliability during next 1100 hours, given it operated for 700 hours.[2+1+2+2=7] 563-82538-2023/05/21 2023/05/21-2022ht74563-82538-2023 538-2023/05/21
