Question

A solid 1.50-in.-diameter brass [G = 6600 ksi] shaft (2) has been stiffened between A and B by the addition of an aluminum-alloy tube (1). The tube has an outside diameter of D1 2.50 in., a wall thickness of t10.10 in., a length of L 12 in., and a shear modulus of G- 3900 ksi. The tube is attached to the brass shaft by means of rigid flanges welded to the tube and to the shaft. (The thickness of the flanges can be neglected for this analysis.) If a torque of 1450 lb-ft is applied to the shaft as shown, calculate the torque carried by the tube Flange Flange Answer: T1 = lb-ft the tolerance is +/-290
