SUMMARY
The method for calculating the breaking stress of brittle steel involves understanding the material's elastic modulus (E) and thermal expansion coefficient (alpha). When a steel rod is heated and then cooled while clamped, it experiences thermal stresses that can lead to fracture rather than elastic deformation, as described by Hooke's Law. The failure mechanism is primarily due to the material's inability to accommodate the induced stresses without yielding, resulting in a brittle fracture.
