(25) A shaft with a circular cross section is comprised of a relatively brittle material. The shaft has shoulder T td fillet of radiusr= ((15+R)/4) mm as shown in Fig. P3. The diameter of the cross-section at the root of the fillet is Figure P3. Shaft with shoulder fillet d = 60.0 mm and the maximum diameter is D=72.0 mm. The member is made of 6061-T6 aluminum (E=69 GPa, v=0.33 and Y=275 MPa). a. Determine the associated calculated stress concentration factor(s) for the given shaft with load T applied as shown in Figure P3 using a figure from appendix D of your book (6th edition posted on BB/lecture slides/stress concentration): i. Write down the figure number from the posted pdf on BB. ii. Show all required calculations for determining the stress concentration factor from that figure. iii. Write the final value of Scc. b. Calculate the maximum stress in the shaft based on the calculated stress concentration factor in part a if the notch sensitivity is q = 0.8 and the applied load is T= (10+S)*100 N-m.
