A wooden beam is loaded by a distributed load w = 8 N/mm as shown in Figure Q4(a).
The cross-section of the beam is shown in Figure Q4(b). Assume that LAB = 2100 mm,
LBC = 2900 mm, W=180 mm, B%= 10 mm, and H = 230 mm, ho=30 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.
Adaptíve marking is still used.
