Question
**Timber Beam Design Exercise** **Objective:** Design a timber beam (S4S) made of Douglas fir to support the load as depicted in the diagram below. **Diagram Analysis:** - **Load Description:** The beam is subjected to a uniform load of 500 pounds per foot (lbs/ft). - **Beam Span:** The total horizontal span of the beam is 12 feet (12'-0"). - **Support Structure:** The beam is supported on one end by a solid wall, indicating a fixed or pinned connection to the wall. **Design Considerations:** When designing the beam, consider factors such as: 1. **Material Properties:** Choose the appropriate size of Douglas fir to accommodate the load while ensuring structural integrity. 2. **Deflection Criteria:** Ensure that the beam deflection does not exceed acceptable limits for safety and functionality. 3. **Stress Analysis:** Calculate the bending stress and ensure it remains within allowable limits for Douglas fir. This exercise aims to apply principles of structural engineering and material science to determine the appropriate dimensions and specifications for the timber beam, considering both safety and efficiency.
