Question
1. Find the forces acting on the members BD and CE. Indicate if it is tension or compression.
The image showcases a truss bridge subjected to external forces. ### Description: - **Bridge Structure**: The bridge consists of interconnected straight members forming a truss with triangular units. - **Supports**: - **Left Support (A)**: Fixed at a point on solid ground. - **Right Support (F)**: Resting on solid ground. - **Dimensions**: - The total span of the bridge is divided into two equal sections of 10 meters each between points A-B, B-D, and D-F. - **Loads**: - **Point B**: Subjected to a 60 kN vertical load. - **Point D**: Subjected to an 80 kN vertical load. - **Angle**: - The angle between member AC and horizontal line AB is 20°. ### Coordinate System: - An XY coordinate system is shown, with: - **X-axis**: Horizontal direction. - **Y-axis**: Vertical direction. This diagram is an example of structural analysis, where the aim is to understand how forces distribute throughout the bridge under given conditions.
