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.
