고체역학 (Beer) — Stress and Strain—Axial Loading: Problem 2.62

2.62 A 2-m length of an aluminum pipe of 240-mm outer diameter and 10-mm wall thickness is used as a short column to carry a 640-kN centric axial load. Knowing that \(E = 73 \text{ GPa}\) and \(\nu = 0.33\), determine (a) the change in length of the pipe, (b) the change in its outer diameter, (c) the change in its wall thickness.
