The length of a wire is cut in half. Why does this change have no effect on the maximum load the wire can support?

The maximum load a wire can support is determined by its material properties, such as its tensile strength and elasticity, rather than its length. Cutting the wire in half does not change these material properties, so the maximum load it can support remains the same.

The maximum load a wire can support is directly proportional to its cross-sectional area and inversely proportional to its length. When the length of the wire is cut in half, the cross-sectional area remains the same. So, the maximum load the wire can support remains the same.
