Unformatted text preview: A and joined securely to a rigid plate at end B . The composite bar, which has a length L 5 550 mm, is twisted by a torque T 5 400 N ? m acting on the end plate. (a) Determine the maximum shear stresses t 1 and 2 in the bar and tube, respectively. (b) Determine the angle of rotation (in degrees) of the end plate, assuming that the shear modulus of the steel is G 5 80 GPa. (c) Determine the torsional stiffness k T of the composite bar. ( Hint : Use Eqs. 344a and b to find the torques in the bar and tube.) A Tube T End plate B Bar L d 3 d 2 d 1 Sec_3.8.qxd 9/27/08 1:13 PM Page 309...
