Question
### Problem 4/5 - Truss Analysis **Problem Statement:** Determine the force in each member of the loaded truss. **Diagram Description:** **Truss Structure:** - The truss is a framework consisting of four members interconnected at joints A, B, C, and D. - Joint A is fixed with a pin support. - Joint B is a roller support. **Geometry:** - The truss forms two triangles, ABD and BAC. - Member AB is horizontal with a length of 6 meters. - Member BD is inclined, connecting joints B and D with a length of 5 meters. - Member AD is also inclined, connecting joints A and D with a length of 5 meters, forming a 45-degree angle with the horizontal. - Member DC is horizontal, with a length of 6 meters. - Member BC is inclined, connecting joints B and C with a length of 5 meters. **Loading:** - A load of 5000 N is applied vertically downward at joint C. **Coordinates and Measurement:** - The horizontal distance between joints A and B is 6 meters. - The horizontal distance between joints B and C is also 6 meters. - The vertical height from points A and B to point D is 5 meters for both members. ### Problem to Solve: - Determine the force in each truss member (AB, AD, BD, BC, and DC) by using methods such as the method of joints or the method of sections. ### Educational Note: Analyzing trusses is a fundamental aspect of structural engineering. It involves determining the internal forces that members of a truss experience in response to external loads. These internal forces help in designing structures to withstand loads without failure. This problem illustrates an example of such analysis. Each member's force can be classified as either tensile or compressive. Typically, calculations start by examining the joints where fewer unknowns are present, applying equilibrium equations to solve for the forces systematically.
