**Problem 10**: Calculate the stored energy in 1 cm³ of an iron crystal due to the presence of \(10^8 \, \text{cm/cm}^3\) of screw dislocations. The shear modulus of iron is \(8.6 \times 10^{10} \, \text{Pa}\) and the Burgers vector equals \(2.48 \times 10^{-10} \, \text{m}\). Assume that the radius of the dislocation core is equal to \(b\).

Answer: Stored energy = 3.2 x 10-3 Joule/cm3
