Extracted text: (a) (b) hot Bo H LAB LBC Cross-section Figure Q4: (a) A wooden beam is loaded by a distributed load, (b) cross-section of the beam. Qa a) Determine the 2nd moment of area of this cross-section in Figure Q4(b)? I= mm* Area moment of inertia Write down the mathematical formula to calculate the final 2nd moment of area for this cross-section: I =


Extracted text: 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 = 1600 mm, LBC = 3400 mm, W=190 mm, Bo = 20 mm, and H = 200 mm, họ=40 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.
