The document provides an example problem and solution from an AMIE exam on material science. The problem involves estimating the fracture strength of a glass sample with a crack half length of 2 micrometers, given the glass's Young's modulus of 70 GNm-2 and specific surface energy of 1 Jm-2. The solution uses a formula for critical fracture stress that relates the stress to the Young's modulus, crack length, and surface energy. Plugging in the given values yields an estimated fracture strength of 150 MNm-2.
