A torque of T = 2.75 kN-m will be applied to the hollow thin-walled aluminum alloy section shown in Figure P6.110. If the section has a uniform thickness of 4 mm, determine the magnitude of the maximum shear stress developed in the section. (Note: The dimensions shown are measured to the wall centerline.)
