Question Details

The maximum load a wire can withstand without breaking, when its length is reduced to half of its original length, will

Options

A

be double

B

be half

C

be four times

D

remain same

Correct Answer :

remain same

Solution :

The correct option is remain same.

Step-by-step Explanation:

The maximum load a wire can withstand without breaking is known as its breaking load. The relationship between the breaking load, the breaking stress of the material, and the cross-sectional area of the wire is given by the formula:
Breaking Load = Breaking Stress × Area of Cross-Section
Here, breaking stress is the maximum force per unit area that the material can sustain before fracturing.

1. Nature of Breaking Stress:
Breaking stress is an intensive (or intrinsic) property of the material. This means it depends solely on the substance the wire is made of (e.g., steel, copper, aluminum) and does not depend on the physical dimensions of the wire, such as its length or total volume.

2. Cross-Sectional Area:
Cutting a wire to reduce its length to half does not alter its thickness. Therefore, the cross-sectional area remains exactly the same.

Conclusion:
Since the breaking stress of the material remains constant and the area of cross-section is unchanged, the breaking load (maximum load) also remains the same. Hence, the capacity of the wire to withstand load does not depend on its length.
