Question

Can you help me with d, e & f please........

A wooden beam is loaded by a distributed load w = 6 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, Bo = 10 mm, and H=210 mm, ho=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) X ω LAB B mm4 LBC 7777 Show steps (Your score will not be affected.)
