The maximum load a wire can withstand without breaking,when its length is reduced to half its original length will be:
Correct answer: D. Remains the same
- A. Doubles
- B. Halved
- C. Four times
- D. Remains the same
Explanation
By halving the length of the wire, its cross-sectional areaeffectively doubles keeping the volume constant. Theincrease in cross-sectional area allows it to withstandgreater load hence the maximum load it can withstanddoubles.

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.
