Question
**Problem Interpretation** The task is to determine the reactions at points \( B \) and \( D \) when \( b = 70 \, \text{mm} \). **Diagram Explanation** The diagram illustrates a mechanical system composed of several key elements: - **Points A, B, C, and D**: Specific points on the structure, with a downward force of 80 N applied at point \( A \). - **Measurements**: - The horizontal distance from \( A \) to \( B \) is \( 250 \, \text{mm} \). - The vertical distance labeled as \( b \) from point \( C \) to point \( B \) is \( 70 \, \text{mm} \). - The curved arm extends out from point \( C \) to \( D \), with a radius of \( 75 \, \text{mm} \). - The horizontal distance from point \( C \) to the attachment at \( D \) is \( 90 \, \text{mm} \). The structure experienced an applied force of 80 N acting vertically downward at point \( A \). To solve for reactions at \( B \) and \( D \), one would likely analyze the forces and moments about the various connections, assuming static equilibrium conditions. This setup is typical in physics or engineering mechanics courses focusing on statics, where determining reaction forces is crucial for assessing structural stability.
