The maximum load a wire can withstand without breaking, when its length is reduced to half of its original length will
Correct answer: A. Double
- A. Double
- B. Be halved
- C. Four times
- D. Remains the same
Explanation
The ability of a wire to withstand a load without breaking is related to its cross-sectional area and its length. By halving the length of the wire, its cross-sectional area effectively doubles, assuming volume remains constant. This increase in cross-sectional area allows the wire to withstand a greater load, specifically double the original. Thus, the maximum load it can withstand doubles. Options B, C, and D are incorrect because they do not accurately describe the relationship between the length and load-bearing capacity of the wire.

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.
