1.Solve Prob. 6–30 except let
w1 = 2.5 in,
w2 = 1.5 in, and the force fluctuates between a tension of 16 kips and a compression of 4 kips. 2. For the part in Prob. 6–30, recommend a fillet radius
r
that will cause the fatigue factor of safety to be the same at the hole and at the fillet.

2. Repeat the requirements of Prob. 6–35 with the following loading conditions: Bending: Fluctuating stress from –40 MPa to 150 MPa Axial: None Torsion: Mean stress of 90 MPa, with an alternating stress of 10 percent of the mean stress
