Unformatted text preview: allowable stress of 6000 psi with D = 2.5 and d = 1.25 inches. What must the maximum allowable stress at the surface of the smaller portion of the shaft be if the fillet radius is 0.3125 in?5000 psi 3. For Problem 4.2, assuming the outer diameter is 40 mm and the inner is 30 mm, determine the moment of inertia of the cross section about the neutral axis in mm4.8.59 x 104 mm4 4. The cross section of a beam is 140 mm x 140 mm. Under load, it is found that the normal stress due to bending is 40 MPa in tension on the bottom and 40 MPa in compression on the top. What is the bending moment in kNm?18.29 kNm 5. True or False? For a beam under pure bending, there are two curvatures. (circle one)True...
