Truss Review

Please provide work

### Structural Analysis Problem **Grid and Diagram Details:** - **Grid Dimensions:** Each grid line represents 1 foot. - **Diagram:** A truss structure is displayed with labeled points, angles, and an applied force. - **Points:** - **Point A:** Located at the bottom left, represents the roller. - **Point B:** At the top, with a horizontal force of 240 lb acting to the left. - **Point C:** Mid-bottom, represents a pin. - **Point D:** At the bottom right. - **Angles:** - **B to A:** 71.565° from the horizontal. - **B to D:** 50.194° from the horizontal. **Tasks:** 1. **Identify Reaction Forces:** - Draw and label reaction forces at points A, C, and D. 2. **Calculate Forces:** - Solve for the following forces and show calculations: - \( R_{\text{Ay}} \) - \( R_{\text{Cy}} \) - \( R_{\text{Cx}} \) - Member A-B - Member A-D - Member B-C - Member B-D - Member C-D **Notes:** - Focus on the equilibrium of forces and moments. - Use trigonometry and static equilibrium equations to find unknown forces. - Ensure all calculations are clearly shown for full understanding. This problem requires understanding of mechanics and static equilibrium principles. It is designed to apply theoretical knowledge to a practical truss analysis problem.
