The answer is one of the options below please solve carefully and circle the correct option Please write clear . Suppose an ideally-prepared test specimen in an R.R. Moore rotating beam test has an ultimate strength of 200 ksi. Further suppose that we have determined the coefficient f to be 0.76.If the specimen is subject to a completely-reversing load of amplitude 108 ksi, how many cycles of life are expected? Hint: keep at least four non-zero digits in any exponents you calculate inintermediate steps.Do not use scientific notation. Blackboard will not understand.
