A solid steel bar of a diameter 1.2 in. is enclosed by a steel tube of outer diameter 1.8 in. and inner diameter 1.4 in. (figure 2). Both bar and tube are held rigidly at end A and joined securely to a rigid plate at B. The composite bar, which is 20 in. long, is twisted by a torque T=4400 lb-in acting on the end plate. It is assumed that the Young's modulus of the steel is E=29*10^6 osi, and Poisson's ratio is v=.25. a) what fraction of the torque is carried by he steel bar? b) determine the max shear stresses in the bar and tube.
