고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.8-3

5.8-3 A simply supported wood beam is subjected to uniformly distributed load q. The width of the beam is 150 mm and the height is 200 mm. Determine the normal stress and the shear stress at point C. Show these stresses on a sketch of a stress element at point C. [From the figure for Problem 5.8-3]: - Load \( q = 5.8 \text{ kN/m} \) - Total span \( L = 3 \text{ m} \) - Point C is located \( 1 \text{ m} \) from the left support (A). - Point C is at a depth of \( 75 \text{ mm} \) from the top surface of the beam. - Cross-section: \( b = 150 \text{ mm} \), \( h = 200 \text{ mm} \).
