A wire of length L can support a load W. If the wire is broken in to two equal parts then how much load can be suspended by one of those cut wires?
- A. Half
- B. Same
- C. Double
- D. One fourth
Step-by-step solution
The maximum load a wire can support in tension depends on its cross-sectional area and material properties, not its length. Cutting the wire into two equal parts does not change the cross-sectional area, so each part can support the same load W as the original wire.
