Anwar Hossain, PhD, PEng; Ryerson University 10 Torsion of Thin-walled tubes-Shear Flow Do example problem: 6-16, 6-17 Probable problems to be solved (time permits) In the class: 6-122,6-124, 6-125 By TA/GA: 6-123, 6-128 K.M. Anwar Hossain, PhD, PEng; Ryerson University Example 6-16 The aluminum alloy (G: 4000 ksi) bar shown in Fig. is subjected to a torque T : 2500 lb . in. Determine the maximum shearing stress and the angle of twist for the 12-in. length. K.M. Anwar Hossain, PhD, PEng; Ryerson University K.M. Anwar Hossain, PhD, PEng; Ryerson University 11 Class problems K.M. Anwar Hossain, PhD, PEng; Ryerson University Class problems K.M. Anwar Hossain, PhD, PEng; Ryerson University K.M. Anwar Hossain, PhD, PEng; Ryerson University 12 Class problems 6-122: A torque of 2.0 kNm will be applied to the hollow, thin-walled, aluminum section shown in Fig. lf the maximum shearing stress must be limited to 40 MPa, determine the minimum thickness required for the section. 6-124: A 500-mm-wide x 3-mm-thick x 2-m-long aluminum sheet is to be formed into a hollow section by bending through360' and welding (butt-weld) the long edges together. Assume a median length of 500 mm (no stretching of the sheet due to bending). If the maximum shearing stress must be limited to75 MPa, determine the maximum torque that can be carried by the hollow section if: a. The shape of the section is a circle. b. The shape of the section is an equilateral triangle. c. The shape of the section is a square. d. The shape of the K.M. Anwar Hossain, PhD, PEng; section is a 150 x 100-mm rectangle. Ryerson University Class problems 6-125: A solid rectangular bar of aluminum alloy (G :4000 ksi) is subjected to the torques shown in Fig. lf T1=10,000 lb-inch, T2 = 30,000 lb-inch, a = 2 inch, b = 3 inch and L1 = L2 = 30 in., determine a. The maximum shearing stress in the bar. b. The rotation of end C with respect to the support at A. K.M. Anwar Hossain, PhD, PEng; Ryerson University K.M.
