The ultimate strength of a sample is the stress at which the sample:
Correct answer: D. Breaks
- A. Remains underwater
- B. Returns to its original shape when the stress is removed
- C. Bends at 180 degrees
- D. Breaks
Explanation
The ultimate strength of a sample is the maximum stress that the sample can withstand before it breaks or fractures.

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.
