![### Mechanics of Materials: Calculating Normal Stress in Composite Columns
#### Column Construction
The column is constructed by gluing together two identical boards. The configuration is shown in the diagram below:
#### Diagram Explanation
- The diagram depicts two wooden boards of identical dimensions glued together to form a column.
- Dimensions of the boards:
- Depth: 300 mm
- Width of each board: 150 mm
- Combined width (after gluing): 250 mm
- The force, denoted as \( P \), is applied at the top of the structure, creating an eccentric load. The force is situated 75 mm from one edge and 50 mm from the other edge of the column.
#### Problem Statement
**Part A:**
Determine the maximum normal stress developed on the cross-section when the eccentric force \( P = 70 \, \text{kN} \) is applied.
Express your answer to three significant figures and include the appropriate units. Enter a negative value if in compression and a positive value if in tension.
\[ \sigma_{\text{max}} = \]
- **Submit** your answer for evaluation, or **Request Answer** for guidance.
