고체역학 (Beer) — Stress and Strain—Axial Loading: Problem 2.14

2.14 The 4-mm-diameter cable $BC$ is made of a steel with $E = 200\text{ GPa}$. Knowing that the maximum stress in the cable must not exceed $190\text{ MPa}$ and that the elongation of the cable must not exceed $6\text{ mm}$, find the maximum load $\mathbf{P}$ that can be applied as shown.
