The given stress-strain graph shows the different changes that occur in a body when stress is applied to it. Which point shows the ultimate strength of the body?
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
Point C represents the ultimate strength of the material. It is the point where the material reaches its maximum stress before fracturing or breaking. Beyond this point, the material undergoes significant plastic deformation or failure.Hence, option C is the correct answer.

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.
