Answer: material, not its dimensions.
- A material, not its dimensions
- B length of the sample only
- C cross-section area only
- D weight of the sample
Correct answer: A. material, not its dimensions
Explanation: Breaking stress is a property of the material itself, independent of the specimen’s size.
A typical stress-strain curve: the initial straight line (Hooke's Law region, slope = Young's modulus) ends at the elastic limit; beyond the yield point, deformation becomes permanent, peaking at the ultimate tensile strength before the wire finally fractures.
Concept context
Stress, strain, Hookes law, and the elastic moduli that describe how solids deform and recover under load.
