Figure 18 Different types of force act on structural members in frame structures. 2. In Figure 19, the diagram shows a feeding tray for birds. This frame structure consists of different sections. It shows a representation of the different sections (1-4) that make up the feeding tray. a) Identify the forces acting on each section of the feeding tray (1-4). (4) b) Copy the diagram. Add arrows to your diagram to show the type of force acting on each section of the feeding tray (1-4). (4) c) As more birds arrive to feed, more weight will be added to the feeding tray. The bracket (Section 1) will start to bend. On your diagram, add a member to the structure to strengthen the bracket.
