Current Attempt in Progress

A cylindrical rod $380$ mm $(15\mathrm{.}0$ in $.)$ long and having a diameter of $10\mathrm{.}0$ mm $(0\mathrm{.}40$ in $.),$ is to be subjected to a tensile load. If the rod is to

experience neither plastic deformation nor an elongation of more than $0\mathrm{.}9$ mm $(0\mathrm{.}035$ in $.)$ when the applied load is $24,500N(5500$ lbf $),$

which of the four metals or alloys listed in the following table is a possible candidate?

Steel alloy

Copper

Aluminum alloy

Brass alloy
