고체역학 (Gere) — Applications of Plane Stress: Problem 8.4-2

8.4-2 Solve the preceding problem using the following data: beam cross section is 100 × 150 mm, length is 3 m, and point load is P = 5 kN at mid-span. Point C is located 25 mm below the top of the beam and 0.5 m to the right of support A. Reference to Problem 8.4-1: A wood beam with a cross section 100 mm × 150 mm is simply supported at A and B. The beam has a length of L and is subjected to point load P at mid-span. Calculate the state of stress at point C. Neglect the weight of the beam.
