A solid cylinder of diameter d = 80 mm is fixed at A. A rigid bar is welded at the other end as shown. A force F is applied in the z-direction and a force 10F is applied in the x-direction. For the most critical location (highest stresses) at A (x=0, y=0, z=r): a) Draw a cube showing the stress components on each coordinate face. b) Find the principal stresses. c) Draw the 3D Mohr circle and indicate the principal stresses location and the magnitude of the maximum shear stress. d) Find the highest force F so that the maximum normal stress is less than 120 MPa and the maximum shear stress is less than 60 MPa. e) Calculate the maximum allowable force F if a groove of radius r = 1.9 mm is machined at x=0. 0.5 m F 0.4 m 10F Stresses equations: r = radius Bending Mc TO I 4 Torsion Tr 70-4 J J 2
