A wooden beam is loaded by a concentrated load P = 2000 N and supported by boundary conditions as shown in Figure Q5(a). The cross-section of the beam is shown in Figure Q5(b). Given that LAB = 2100 mm, LBC 2900 mm, Bo=10 mm, = 20 mm, and H = 240 mm, ho=200 mm, h₁ =20 mm, determine the following quantities below: B₁ = Notes: Sign of forces and moments: We define the coordinates below in the question. We assume (1) the positive direction of a vertical force points downwards; (2) the positive direction of a horizontal force points to the right; and (3) the positive direction of a moment is anti-clockwise. Decimal points: any decimal points are fine (typically 2 decimal points) and all the numerical questions have a 10% error tolerance. Method marks: Method marks are considered using adaptive marking. The error will be carried forward, even if your answers to the first few questions are wrong, you can still get marks if the methods for the following questions are correct. Steps are also enabled so that you will gain marks for the method. You will not lose marks no matter if your steps are correct or not.
