SITUATION: A solid steel bar of diameter d1 = 25.0 mm is enclosed by a steel tube of outer diameter d3 = 37.5 mm and inner diameter d2 = 30.0 mm. Both bar and tube are held rigidly by a support at end A and joined securely to a rigid plate at end B. The composite bar, which has a length L = 550 mm, is twisted by a torque T = 400 N-m acting on the end plate. 1. Determine the maximum shear stress (MPa) in the tube. A. 36.2 C. 32.7 B. 49.0 D. 44.9 2. Determine the angle of rotation (in degrees) of the end plate, assuming that the shear modulus of the steel is G = 80 GPa. A. 1.12 C. 0.75 B. 1.50 D. 1.03 3. Determine the torsional stiffness (kN-m) of the composite bar. A. 28.9 C. 33.5 B. 22.3 D. 32.4 Thanks for watching! Comment for questions and suggestions for future lecture in this series.
