![**Equations 7.1a and 7.1b**, expressions for Burgers vectors for FCC and BCC crystal structures, are of the form:
\[ \mathbf{b} = \frac{a}{2} \langle u v w \rangle \]
where \( a \) is the unit cell edge length. Also, since the magnitudes of these Burgers vectors may be determined from the following equation:
\[ |\mathbf{b}| = \frac{a}{2} (u^2 + v^2 + w^2)^{1/2} \]
determine values of \(|\mathbf{b}|\) for aluminum and chromium. You may want to consult **Table 3.1**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F46029127-96a5-4dc2-997a-3c090d1aab2d%2Fcf005b33-521e-40b6-a732-8283586bbf36%2Fbdsrhno_processed.png&w=3840&q=75)
