A wire can support a maximum load of $W$ . If the wire is cut in $2$ equal parts and joined in parallel, what is the maximum load it can now support.

Answer:

Solution:

Breaking load depends on cross-sectional area, not on length.

Each half has the same area as the original, so each half supports $W$ .

In parallel, the two halves share the load: maximum load $= W + W = 2 W$ .
