고체역학 (Beer) — Stress and Strain—Axial Loading: Problem 2.66

2.66 A line of slope 4:10 has been scribed on a cold-rolled yellow-brass plate, 6 in. wide and 1/4 in. thick. Knowing that \(E = 15 \times 10^6\) psi and \(\nu = 0.34\), determine the slope of the line when the plate is subjected to a 45-kip centric axial load as shown.
