The breaking stress of a wire depends upon
Correct answer: C. Material of the wire
- A. Length of the wire
- B. Radius of the wire
- C. Material of the wire
- D. Shape of the cross section
Explanation
The breaking stress of a wire is a measure of the maximum stress that the material can withstand before failure. It is an intrinsic property of the material, determined by its molecular structure and bonding. Therefore, it depends on the material of the wire. The other factors, such as the length, radius, and shape of the cross-section, influence the load-bearing capacity and stress distribution but do not affect the breaking stress itself.

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.
