$\varepsilon_x = \dfrac{\sigma_x}{E} - \nu \dfrac{\sigma_y}{E} = 0$
$\sigma_x = \nu \sigma_y$
Where
σx = tangential stress
σy = longitudinal stress
σy = Py / A = 3140 / (π × 2.05 × 0.05)
σy = 9751.15 psi
Thus,
$\sigma_x = 0.30 (0.15 )$
$\sigma_x = 9430 / \pi \, \text{ psi}$
$\sigma_x = 2925.34 \, \text{ psi}$ answer

Why is the diameter 2.05 in
Why is the diameter 2.05 in and not 2 in only?
We use nominal diameter to
We use nominal diameter to get the nominal length.
