A1.6 Figure A1.6 shows a 1-in. solid round shaft supported by self-aligning bearings at A and B. Attached to the shaft are two chain sprockets that are loaded as shown. Treat this as a static loading problem, ignoring fatigue and stress concentration. Identify the specific shaft location subjected to the most severe state of stress, and make a Mohr circle representation of this stress state. 1-in.-dia. shaft 2 in. 1000 lb 3 in. 4 in 500 lb 4 in. Figure A1.6 3 in. A1.7 Figure A1.7 shows a cylinder internally pressurized to a pressure of 7000 psi. The pressure causes tangential and axial stresses in the outer surface of 30,000 and 20,000 psi, respectively. Determine the maximum shear stress at the outer surface. 20 ksi Free surface, 3=0 30 ksi Figure A1.7
