Question
The beam in (Figure 1) is made from three boards nailed together as shown.
If the moment acting on the cross section is M=500N⋅m, determine the maximum bending stress in the beam. Express your answer to three significant figures and include appropriate units.
Transcribed Image Text:The image shows a wooden step block featuring detailed dimensions and structure suitable for an educational context.
**Description:**
The block consists of a top surface and two legs. Here are the key dimensions and features:
- **Top Surface:**
- Width: 200 mm
- Thickness: 25 mm
- **Legs:**
- Height: 150 mm
- Thickness: 20 mm
- Depth: 220 mm (200 mm at the main base plus an additional 20 mm thickness at the end)
The wooden block design is reinforced with multiple screws or bolts, indicated by dots on the top surface.
**Diagram Explanation:**
- The arrow marked with "M" suggests a moment or bending action applied at the central region between the legs of the step, implying a focus on understanding structural integrity and forces acting on the block.
This illustration can help in exploring topics such as structural mechanics, material stability, and the effects of bending moments.
