Use the definitions of Poisson's ratio

The year is $2143$ and the polar ice caps have melted. You're on vacation in New Orleans and the levee has sprung a perfectly square with a linear dimension of $0\mathrm{.}25142.$ You recall that the modulus of steel is around $30,000$ ksi and that the Poisson's ratio of metals is $=1/3$ You find a steel bar with a square cross section of $0\mathrm{.}25"$ linear dimension. How much axial force would you have to continuously apply to the rod for it to plug the hole? Express your answer in kips $(1000$ pounds$-$force$).$
