Problem 3: Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 43.1° and 47.9°, respectively, with the tensile axis. If the critical resolved shear stress is 20.7 MPa (3000 psi), will an applied stress of 45 MPa (6500 psi) cause the single crystal to yield? If not, what stress will be necessary?

Problem 1 (10 pts) It is required to manufacture a 2.5 mm diameter copper rod from larger diameter stock by drawing. The rod should have a tensile strength of 300 MPa or more, a yield strength of 200 MPa or more, and ductility of 10% or more. Determine (a) the range of%CW which will allow achieving those properties, and (b) within this range clearly pick a certain%CW and determine the corresponding diameter of the starting stock. yield strength (MPa) tensile...

3. (20 pts. total) The primary slip plane for a BCC structure is the (110 family of planes although slip can also occur on alternate planes. a. (3 pts.) On the left cube below, draw and label two planes from the (110 family of planes. b. (3 pts.) On the right cube below, two alternate slip planes are shown. What are the Miller indices of these planes? (Note: The blue plane intersects the y-axis at 1/2 and the z-axis at...
