고체역학 (Gere) — Applications of Plane Stress: Problem 8.4-4

8.4-4 A cantilever beam with a width \(b = 100 \text{ mm}\) and depth \(h = 150 \text{ mm}\) has a length \(L = 2 \text{ m}\) and is subjected to a point load \(P = 500 \text{ N}\) at \(B\). Calculate the state of plane stress at point \(C\) located \(50 \text{ mm}\) below the top of the beam and \(0.5 \text{ m}\) to the right of support \(A\). Also find the principal stresses and the maximum shear stress at \(C\). Neglect the weight of the beam.
