(a) In the manner of Equations 7.1a, 7.1b, and 7.1c, specify the Burgers vector for the simple cubic crystal structure. Its unit cell is shown in Figure 3.24. Also, simple cubic is the crystal structure for the edge dislocation of Figure 4.3, and for its motion as presented. You may also want to consult the answer to Concept Check 7.1.
(b) On the basis of Equation 7.10, formulate an expression for the magnitude of the Burgers vector, |b|, for simple cubic.
