A wooden beam is loaded by a distributed load ww = 6 N/mm as shown in Figure Q4(a). The cross-section of the beam is shown in Figure Q4(b). Assume that LAB = 3000 mm, LBC = 2000 mm, W=190 mm, B0 = 10 mm, and H = 220 mm, h0=40 mm. Units: use N, mm, MPa as consistent units for all calculations. Decimal points: any decimal points are fine a)Determine the 2nd moment of area of this cross-section in Figure Q4(b)? b)Calculate support reactions in A and C, remember the sign of the force. Reaction force at point A: x-direction: XA= y-direction: YA= Reaction force at point C: x-direction: XC= y-direction: YC= c)Calculate the equations of shear force V(x) and bending moment M(x). Type the mathematical expressions or constants. Section AB: Section BC:
