Question
The problem involves determining the maximum allowable force \( P \) that can be applied to a simply-supported beam composed of three boards nailed together. Here are the details provided: ### Beam Specifications: - **Shear Stress**: The wood has an allowable shear stress of \( \tau_{\text{allow}} = 1.5 \, \text{MPa} \). - **Bending Stress**: The allowable bending stress is \( \sigma_{\text{allow}} = 9 \, \text{MPa} \). - **Nails**: - Spacing: \( s = 77 \, \text{mm} \). - Shear Strength: \( 1.5 \, \text{kN} \). ### Task: Calculate the maximum force, \( P \), applying the above constraints, and express your answer to three significant figures including the units. ### User Input: - The user attempted to input \( P = 8.9 \, \text{kN} \) and received feedback indicating the answer is incorrect with three attempts remaining. ### Beam Diagram Description: The diagram shows: - The beam is supported at points \( A \) and \( B \), with point \( P \) applied at the center of the span. - Total span of the beam is \( 2 \, \text{m} \) (1 m from support \( A \) to \( P \) and 1 m from \( P \) to support \( B \)). - Cross-sectional view displays three layers: - Top and bottom layers are \( 100 \, \text{mm} \) wide and \( 25 \, \text{mm} \) thick. - Middle layer is \( 200 \, \text{mm} \) wide and \( 25 \, \text{mm} \) thick. ### Interaction: - Users can submit answers, request answers, or provide feedback. - The interface confirms submissions and tracks attempts remaining.
