### Summation of Forces in Cartesian Vector Notation **Question:** 1. What is the resultant summation of forces F_{CA} and F_{CB}? Write the resultant force in Cartesian vector notation. Please retain your answer as it will be needed for other problems. **Diagram Explanation:** The diagram provided exhibits a three-dimensional structure with two force vectors emanating from the top of a tower or pole. - **F_{CA}:** This force vector is labeled as \(400 \text{ lb}\) and points towards point A (from the top of the pole). It is broken down into its components: - 5 ft along the negative x-axis - 5 ft along the positive y-axis - **F_{CB}:** This force vector is labeled as \(500 \text{ lb}\) and it points towards point B (from the top of the pole). The detailed dimensions for this vector are not fully visible but appear to align diagonally from the pole to the base. ### Solution: To find the resultant force \( \mathbf{F_R} \), we need to determine the Cartesian vector components for both \( \mathbf{F_{CA}} \) and \( \mathbf{F_{CB}} \). Once these components are available, summing them will give us the resultant force in Cartesian form. (Note: A more detailed breakdown of the exact vector components would typically be needed for precise calculation, including magnitude and direction cosines based on the provided geometric layout. For simplicity, if additional data were visible or provided, the individual steps and calculations would follow accordingly.)

**Question:**
1. What is the resultant summation of forces F_{CA} and F_{CB}? Write the resultant force in Cartesian vector notation. Please retain your answer as it will be needed for other problems.
**Diagram Explanation:**
The diagram provided exhibits a three-dimensional structure with two force vectors emanating from the top of a tower or pole.
- **F_{CA}:** This force vector is labeled as \(400 \text{ lb}\) and points towards point A (from the top of the pole). It is broken down into its components:
- 5 ft along the negative x-axis
- 5 ft along the positive y-axis
- **F_{CB}:** This force vector is labeled as \(500 \text{ lb}\) and it points towards point B (from the top of the pole). The detailed dimensions for this vector are not fully visible but appear to align diagonally from the pole to the base.
### Solution:
To find the resultant force \( \mathbf{F_R} \), we need to determine the Cartesian vector components for both \( \mathbf{F_{CA}} \) and \( \mathbf{F_{CB}} \). Once these components are available, summing them will give us the resultant force in Cartesian form.
(Note: A more detailed breakdown of the exact vector components would typically be needed for precise calculation, including magnitude and direction cosines based on the provided geometric layout. For simplicity, if additional data were visible or provided, the individual steps and calculations would follow accordingly.)
