Question
The image contains a structural diagram of a truss supported by a hinge at point A and a roller at point E. The truss comprises members including BC, GC, and GF. The given spans in the truss structure are all 6.0 meters. Two point loads are applied downward: a 30 kN load at point B and a 45 kN load at point F. Key features and annotations include: 1. **Truss Structure:** - The truss is symmetrically constructed with triangular sections. - Angles of 60° are present between certain members, indicating equilateral triangles in some sections. 2. **Supports:** - Point A has a hinge support, allowing rotation but restricting translation. - Point E has a roller support, permitting movement along the surface but restricting perpendicular displacement. 3. **Applied Loads:** - A 30 kN load is applied at point B. - A 45 kN load is at point F. 4. **Annotations:** - The text highlights the absence of reaction forces with comments like "Where is your reactions?" and "Where is your FBD for the supports?" suggesting a need to include Free-Body Diagrams (FBD) for clarity. - It emphasizes the importance of identifying these reactions when solving for forces in truss members. 5. **Objectives:** - Determine forces in members BC, GC, and GF using the method of sections. - Consider whether the forces are in tension or compression. This diagram is part of an exercise aimed at understanding how to analyze forces in truss structures using statics principles. The annotated comments serve as feedback, encouraging thorough analysis and inclusion of essential supporting reactions.
