Q: the original wire is 3.8m, and it stretches 7mm?
A: I believe the stretch will be mostly in the copper portion,
but could not tell you the load - you must have a table
or a formula to compute this.

The force(load )is proportional to the elongation you must determine the proportionality constant from empirecal table.
