1. A torque applied to a solid rod of radius r causes the elastic region to extend a distance r/2 from the center of the rod. If the torque is then removed, determine the residual shear stress distribution.
2. The outer diameter of a hollow shaft is twice its inner diameter. Determine the residual stress pattern after the limit torque has been applied and removed.
What in your refuse might have been reusable (as distinct from recoverable), and if you had reused it, how much would this have reduced the refuse?
