6122: A torque of 2.0 kNm will be applied to the hollow, thinwalled, aluminum
section shown in Fig. lf the maximum shearing stress must be limited to 40
MPa, determine the minimum thickness required for the section. 6124: A 500mmwide x 3mmthick x 2mlong aluminum sheet is to be
formed into a hollow section by bending through360' and welding (buttweld)
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 100mm rectangle.

6125: A solid rectangular bar of aluminum alloy (G :4000 ksi) is
subjected to the torques shown in Fig. lf T1=10,000 lbinch, T2 =
30,000 lbinch, 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;
