please someone answer this, need this badly

5 0/ 1 point A circular shaft is subjected to a random cyclic torsional load. During a typical 30 seconds of operation, the number of cycle at each stress level is as follows, 8 cycles at T = $15.8 ksi, 7 cycles at T = 123.5 ksi, 2 cycles at T = 131.5 ksi. Using the following SN curve, estimate the fatigue life of the shaft. [hr] 56 S (ksi (log)) 31.5 23.5 17 10' (2.8 x10') (1.53 x10') 106 N (cycles (log))
