Question
**Problem 2 (Pro 3.25 Textbook):** Identify the zero-force members in the trusses below. **Diagram Explanation:** The diagram illustrates a truss structure with several members and joints. The truss is vertically oriented and appears to be supported at the bottom by two fixed supports at points A and B. An external force \( P \) is applied horizontally to the left at the top joint I. Key elements include: - **Joints:** Indicated by points A, B, C, D, E, F, G, H, and I. - **Members:** Structural components connecting the joints, forming triangles and supporting the structure: - Vertical members (e.g., AC, EG) - Horizontal members (e.g., EF, GH) - Diagonal members (e.g., AD, EF, BI) To solve this problem, determine which members experience no force under the applied load \( P \). Zero-force members often occur in specific configurations, such as when two non-collinear members meet at a joint unstressed by external forces, or when three members form a truss joint with no external load. This type of analysis helps in understanding which members can be removed without affecting the structural integrity, optimizing material usage.
