고체역학 (Gere) — Stresses in Beams (Advanced Topics): Problem 6.4-7

6.4-7 Solve the preceding problem for a cantilever beam with data as \( b = 100 \text{ mm} \), \( h = 200 \text{ mm} \), \( L = 2 \text{ m} \), \( P = 2 \text{ kN} \), and \( \alpha = 45^\circ \). [Preceding Problem 6.4-6 Statement]: A wood cantilever beam with a rectangular cross section and length \( L \) supports an inclined load \( P \) at its free end (see figure). Determine the orientation of the neutral axis and calculate the maximum tensile stress \( \sigma_{\text{max}} \) due to the load \( P \).
