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,

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.
