A wooden beam is loaded by a distributed load w = 5 N/mm as shown in Figure Q4(a). The cross-section of the beam is shown in Figure Q4(b). Assume that LAB = 1700 mm, LBC = 3300 mm, W=180 mm, B, = 20 mm, and H = 210 mm, ho=20 mm. %3D Units: use N, mm, MPa as consistent units for all calculations. Decimal points: any decimal points are fine and all the numerical questions have a 10% error tolerance. Steps: Fill the gaps in the "steps" to get some marks from the working-out process. Adaptive marking is still used. (a) (b) hot Во H B LAB LBC Cross-section W Figure Q4: (a) A wooden beam is loaded by a distributed load, (b) cross-section of the beam.
