Unformatted text preview: (2). (b) If the shear stress in shaft (1) must be limited to 40 MPa, determine the minimum acceptable diameter for shaft (1) if a solid shaft is used. 6.86 A solid 1.50-in.-diameter brass [G = 5,600 ksi] shaft [segments (1), (2), and (3)] has been stiffened between B and C by the addition of a cold-rolled stainless steel tube (4). The tube has an outside diameter of 3.50 in., a wall thickness of 0.12 in., and a shear modulus of G = 12,500 ksi. The tube is attached to the brass shaft by means of rigid flanges welded to the tube and to the shaft. If a torque of 400 lb-ft is applied to the shaft as shown, determine: (a) the maximum shear stress magnitude in segment (1) of the brass shaft. (b) the maximum shear stress magnitude in segment (2) of the brass shaft (i.e., between flanges B and C) (c) the maximum shear stress magnitude in the stainless steel tube (4). (d) the rotation angle of end D relative to end A. For practice 6.21 6.55 6.90...
