2. A non-rotating solid round bar with diameter of 2-in has a groove cut to a diameter of 1.8-in, with a groove radius of 0.1-in. The bar is loaded with a repeated bending load that causes the bending moment at the groove to fluctuate between 0 and 25000 lbf-in. The bar is hot-rolled AISI 1095, but the groove has been machined. Determine the factor of safety guarding against first-cycle yielding and the factor of safety against fatigue failure based on: 1) Goodman; 2) ASME elliptical.
3. A solid round bar with diameter of 2.75-in has a groove cut to a diameter of 2.5-in, with a radius of 0.125-in. The bar is not rotating.

4) Ball bearings support the rotating axle shown below at points A and D. The rotating axle is loaded by a stationary (non-rotating) force of F = 6.8 kN. In the drawing below, all dimensions are in mm, and all geometry changes (steps in the diameter shaft) have a fillet radius of 3 mm. The axle is machined from AISI cold-drawn steel with an ultimate strength of S_u = 690 MPa and a yield strength of S_y= 580 MPa. Calculate the safety factor at the 6.8 kN load and points B and C, which experience moderate bending moments with a geometric feature that causes a stress concentration.
