Physics Question on Stress and Strain
The maximum load a wire can withstand without breaking, when its length is reduced to half of its original length, will
A
be doubled
B
be half
C
be four times
D
remain same
Answer
remain same
Explanation
Solution
Breaking force = Breaking stress ? Area of cross-section. When the wire is cut to half, there is no change in the area of cross-section of the wire. Therefore, there is no change in the maximum load (i.e., breaking force) the wire can support.
