Stress and strain — practice question

There are two wires that have the same Young modulus $E$ and cross-sectional area $A$, although their lengths $L$ are different, and each wire is acted on by a different tensile force $F$. The extension $e$ of both wires is equal. The table headings list four separate quantities. Which of these quantities have equal values, and which have unequal values, for the two wires?
