1. Consider a BCC unit cell below. a) Determine the Miller indices for the red triangle (plane AEC). (Note: show your procedure. Do not jump to the final answer.) (10 points) b) In our Lecture Note for Chapter 3 (IIc_chapter3.pdf, Slide \#24), we stated that the AEC plane does not contain the body-centered atom. Please show why this is true. (5 pints) Hint: you can show the DBEF plane. c) The elastic modulus is primarily governed by the atomic packing density. Particularly the tensile modulus is larger if the linear density along the tensile axis is larger. Using this argument, which one of $E_{DE}$ and $E_{BE}$ is larger? Justify your answer.
