A metal rod with a 0.5 inch diameter is subjected to a 2000 lb tensile load. Calculate the resulting diameter of the rod after loading. Assume that the modulus of elasticity is 10,000,000 psi, Poisson's ratio is 0.33, and the yield strength is 21,000 psi.

2. Relevant equations

I'm not really sure how to go about this problem, below is how I started going about it but I'm not sure if I'm on the right track or not.

3. The attempt at a solution

σ = P/A = 2000 psi / ( (Pi(0.5^2)/4)) = 1.02 (10^4) psi

€_{y}= (σ_{y}- v(σ_{z}+ σ_{x}) ) / E

= (1.02(10^4) - 0.33 * 0) 10,000,000 psi

€_{y}= 0.00102 in/in

Now I'm not really sure what next, or even if what I did to this poing is correct.

Any help will be appreciated!
