A witness stated that two people were working on one board simultaneously, as shown in Figure 6 below. This is prohibited. A 500 mm 90 kg C -1.5 m Figure 6 FBD of the scaffold board under vertical load 70 kg D 500 mm. B Show description For this vertical load shown (which excludes the UDL as requested by the lead engineer): i. Calculate the support reaction forces at A and B to an appropriate significant figure. Take g = 9.81 ms-2. (10 marks) ii. With these results, sketch a shear force and bending moment diagram for the beam. You will need to follow and label the three-step process from Chapter 8.2.
