The strain energy of a dislocation normally varies as the square of its Burgers vector. One may see this by examining Eqs. 4.19 and 4.20. This relationship between the dislocation strain energy and the Burgers vector is known as Frank’s rule. Thus, if b= a{hkl}, where a is a numerical factor, then:
A system is tested for faults once per hour. If there is no fault, none will be detected. If there is a fault, the probability is 0.8 that it will be detected. The tests are independent of one another.
a. If there is a fault, what is the probability that it will be detected in 3 hours or less? b. Given that a fault has gone undetected for 2 hours, what is the probability that it will be detected in the next hour? c. What is the mean number of tests that must be conducted in order to detect a fault?
