The maximum load that a wire can sustain...

The maximum load that a wire can sustain is W. If the wire is cut to half its value, the maximum load it can sustain is

Verified by Experts

Since breaking load = breaking stress `xx` area, is free from the length of elastic wire, therfore, if the cable is cut to half of its original length, there is no charge in its area of cross section and breaking stree. Hence there is no effect on the maximum load ( breaking load), the cable can support.
