Label the cranial bones 1-4. 1.   2.   3.   4.    

The shaft shown below is made from 1040 steel with properties of Sy = 71 ksi and Sut = 85 ksi with dimensions given, and the journal bearings at A & B prevent motion of the shaft but do not create reaction moments. Forces F1 = [F1]0 lbf and F2 = [F2]0 lbf are applied in the vertical direction to the shaft as it rotates. Determine the minimum diameter needed for the shaft so that it will last an estimated N = [N],000 cycles before fatigue failure. Use an endurance limit of Se = 40 ksi.Hint: The critical location will be at bearing B.Enter your answer in units of inches and rounded to 3 decimal places. Write down all your work to scan and submit. L1 = [L1] inch, L2 = [L2] inch, L3 = [L3] inch
