Question

the previous answer i got from this website was wrong, part A must be an integer or decimal part B Xa and Xc are = 0

b) Calculate support reactions in A and C, remember the sign of the force. Reaction force at point A: x-direction: XA= Reaction force at point C: x-direction: Xc= N, y-direction: YA= N, y-direction: Yc= N N

A wooden beam is loaded by a distributed load w = 7 N/mm as shown in Figure Q4(a). The cross- section of the beam is shown in Figure Q4(b). Assume that LAB = 1800 mm, LBC = 3200 mm, W=190 mm, B₁ = 30 mm, and H = 210 mm, h=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) A 777777 W LAB = B LBC Bo Cross-section hot H X yx Figure Q4: (a) A wooden beam is loaded by a distributed load, (b) cross-section of the beam.
