Extracted text: A wooden beam is loaded by a distributed load 5 N/mm as shown in Figure Q4(a). The cross-section of the beam is shown in Figure Q4(b). Assume that Lan=1700 mm, Lc 3300 mm, W=180 mm, B = 20 mm, and H= 210 mm, hy=20 mm. 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) w hol Bo Lục Cross-section Figure Q4: (a) A wooden beam is loaded by a distributed load, (b) cross-section of the beam. Qa a) Determine the 2 moment of area of this cross-section in Figure Q4b)?
