A $0\mathrm{.}750-$in$-$diameter carbon steel tension rod is $5\mathrm{.}30$ ft long and carries a load of $15\mathrm{.}00$ kip $.$ Find the tensile stress, the total

deformation, the unit strains, and the change in the rod diameter.

The tensile stress of the rod is

kpsi.

The total deformation of the rod is

in$.($Round the final answer to four decimal places.$)$

The unit strain in the rod is

$.$

The change in the rod diameter is

$x+2$

${10}^{-6}$ in$.($Include a minus sign if necessary.$)$
