Question
**Problem 4.161** Determine the forces in members EF, BF, and BC. **Figure P4.161** This figure illustrates a truss system with a series of connected members. Key elements in the diagram include: - **Load Forces**: There are two point loads acting on the structure: a 5.34 kN force acting downwards at point F and a 6.67 kN force acting downwards at point G. - **Support Points**: The truss is supported at points A and D, which are symmetric supports positioned beneath the horizontal members. - **Geometric Details**: - The horizontal distance between supports A and D is 4.57 meters, divided as follows: 1.83 meters from A to B, 0.915 meters from B to C, and 1.83 meters from C to D. - The vertical height from the base line (passing through A, B, C, D) to the top point F is 1.27 meters. Additionally, there is a vertical measurement of 1.83 meters from each of the supports A and D directly upwards. - **Truss Members**: Identified as line segments connecting the points, notably including members EF, BF, and BC, whose forces need to be determined. This figure is essential for analyzing the static equilibrium of the structure to find the force in specific truss members using methods such as the method of joints or method of sections.
