A 1035 hotrolled steel shaft shoulder the small diameter d i
     A 1035 hot-rolled steel shaft shoulder the small diameter d is 25.4 mm, the  diameter D is 33.8mm, and the fillet radius is 1.69mm. At the shoulder the subjected to a completely reversed bending moment of  70N-m, accompanied  a steady torsion of 45N-m. Using a reliability of 99.9%, Determine the  factor of safety of the design using DE-Goodman criteria and yielding factor of safety? (50%) 
  
  Solution
Hello Dores..The 33.8 mm diameter is for which parameter?
