ENME 382 Section 0201 Homework# 3 Due in class: Friday, Feb. 26, 2010 1. Callister 3.27 Within a cubic unit cell, sketch the following directions: (a) [10 2 ] , (c) [ 2 12] , (b) [3 1 3] , (d) [301]. 2. Callister 3.29 For tetragonal crystals, cite the indices of directions that are equivalent to each of the following directions: (a) [011] (b) [100] 3. Callister 3.35 Sketch within a cubic unit cell the following planes: (a) (012), (c) (10 1 ) , (b) (3 1 3) , (d) (2 1 1) . 4a. For an FCC metal like gold (Au): i. Sketch/draw the unit cell in 3-D ii. Draw the (111) in the unit cell in i iii. In a separate drawing, show the atomic arrangement on the (111) plane. Indicate which atoms are touching (if any) and where they are touching.
