Unformatted text preview: (Callister 3.36) 6. What is the linear density of atoms along the  direction in an FCC unit cell. Questions for thought: 7. Would the elastic modulus be the same in the  and the  direction in a BCC metal (such as iron)? Why or why not? 8. Why is the elastic modulus of single crystal aluminum higher in the  direction than in the  direction as shown in Table 3.7 of Callister? 9. Would you expect the elastic modulus of a bulk aluminum sample to be higher in one direction than another? Why or why not? 10. What is the angular relationship between a direction in a cubic crystal and the plane with the same Miller indices?...
