Such substances which break soon after they cross the elastic limit is called
Correct answer: B. brittle substances
- A. weak substances
- B. brittle substances
- C. ductile substances
- D. polymeric substances
Explanation
Brittle substances are those materials that break or fracture soon after they exceed their elastic limit. They lack plastic deformation and undergo very little or no elongation before fracturing. Examples of brittle substances include ceramics, certain types of glass, and some metals under certain conditions

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
