The rotating shaft in the figure is machined from AISI 1020 CD carbon steel and supported by two bearings that create reaction forces A and B. It is subjected to a force of F = 1350 lbf and applied torque of T = 7000 lbf-in. Dimensions for the shaft are listed below:L1 = 10 in, L2 = 10 in, L3 = 3 in, L4 = 8 in, d0 = 1.25 in, d1 = 1.625 in, d2 = 1.875 in, d3 = 1.75 in Note: The transition between each of the diameters has a fillet with r = ⅛-inch. Determine the maximum normal bending stress and torsional shear stress at point C including the stress concentration. Enter value rounded to 1 decimal place in units provided. σC_max = [sigma] ksiτC_max = [tau] ksi The Stress Concentration charts can also be viewed here.
