고체역학 (Gere) — Stresses in Beams (Advanced Topics): Problem 6.4-8

6.4-8 A 2-m-long cantilever beam is constructed using an IPN 320 section. Load $P$ acts in an inclined direction at the free end (see figure). Determine the allowable load $P$ that can be carried by the beam if the maximum permissible tensile and compressive stresses are $150 \text{ MPa}$. Include the weight of the beam in the calculations.
