If length of the wire is doubled, then it can hold ___________.(Cross-sectional area remains same)

CONCEPT:

• Breaking Stress: It is also called ultimate tensile stress. It is the maximum stress a material can stand before it breaks.
• Tensile stress:  The force applied along a rod divided by the cross-sectional area of the rod perpendicular to the applied force is called tensile stress.

\(\rm Tensile~stress = {Force \over Cross ~section ~area}\)

EXPLANATION:

• From the definition, it is clear that the breaking stress of a rod is given by:

Stress = F/A

• If we change the area, there may be a change in the load to break a rod.
• Since there is no role of length in calculating the breaking stress, so change in length will not change the breaking stress.
• So if the length of the wire is changed, it will still hold the same load as the initial value.
• Hence the correct answer is option 1.
