A wire, made of a certain material of length-l and area of cross section-a can withstand a maximum load =W without breaking. If, another wire of the same material and cross-sectional area is used with double the original length, what will be the maximum load that the wire can withstand, without breaking?
- A Would be four times =4W
- B Will be doubled to 2W
- C Remains the same =W
- D Will be halved to 0.5W
Answer & Solution
Correct Answer
(C) Remains the same =W
Step-by-step Solution
Detailed explanation
Breaking stress is a property of the material and is independent of the dimensions of the wire. The maximum load a wire can withstand is given by the product of breaking stress and the cross-sectional area. Maximum load = Breaking stress \(\times\) Area of cross section Since…
