Similar setup to the previous homework (and the problem we did together in class): a structure comprised of two attached cylinders, one on top of the other, both of equal lengths (50 cm). The bottom cylinder is solid (radius = 10 cm) and the top cylinder is hollow (outer radius = 8 cm, thickness = 2 cm); the assembly is attached to a rigid base. If a counterclockwise 40kN m torque is applied at the top of the top cylinder and a clockwise 30kN m torque is applied at the top of the bottom cylinder, find the max shear stress experienced by each cylinder. Let's use the same problem as above but reset, just so that errors do not propagate: consider the same setup but with Tmax = 13.8 MPa for the bottom cylinder and Tmax = 117.6 MPa for the top cylinder. Now consider that in addition to these, an axial tensile force of 20 kN is applied to the assembly. a. Construct a stress element representing the state of stress on each cylinder. For conventions, use the axial (upwards) direction as +y, the right as +x, and "out of page" as +z. b. Determine the stresses n, t, & Tnt acting on the upper (smaller) cylinder's stress element if it is rotated by 40 counterclockwise.
