A single crystal of an FCC metal has a tensile stress applied parallel to [001]. The critical resolved shear stress is 0.5 MPa. What are the applied stresses necessary to cause slip in the (111) plane along [-101], [10-1], and [0-11] directions

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
