Consider the pulley assembly below. A torque of 500 Nmm is applied to the end of a 2mm diameter shaft, which is transmitted to pulley A, which has a radius of 5 mm. Pulley A has a fan belt under tension, which is angled 20 down from the z axis. The belt tension on the loose side of Pulley A is 25% of that on the tight side. Assume the shaft is running at a constant speed. (a) Determine the belt tensions on the Pulley A. (b) Identify the critical location along the shaft. (c) Identify the critical element location on the cross-section by drawing a dot on the figure in the answer box. (d) Calculate the maximum bending stress state and torsional shear stress of the shaft. (e) Calculate the Principal Stresses and Maximum Shear Stress of the critical element. Report your final answers here: T=500 Nmm C (a) T = N T2= N (b) x mm T2 B (d) Obend MPa A Ttorsion MPa (e) = MPa T 02= MPa 03= MPa Tmax= MPa 15 mm 5 mm
