3 0/1 point A cantilevered stepped circular shaft is made of steel with an ultimate strength of S. The shaft is machine surfaced and is subjected to a cyclic torsional load at its free end as shown. If the resulting maximum mean shear stress T8.3 ksi and the maximum alternating shear stress Ta=20.9 ksi, using the constant life diagram shown, determine the corresponding fully reversed stress level obtained from where the Goodman line intercepts the vertical Taxis.[ks] 231 -O t, (ks) 565 175 Je be 10'6 (ks) 64
