The maximum load a wire can withstand without breaking when its length is reduced to half of its original length, will:
1. be doubled
2. be halved
3. be four times
4. remain the same
(d) Hint: Breaking stress is independent of the length of the wire.
Step 1: Find the breaking stress of the wire.
We, know that, ...(i)
When the length of the wire changes, the area of the cross-section remains the same.
Hence, the breaking force will be the same when length changes.
