## 3. Calculation Book
### 3.1 Basic parameters calculation of lamp pole
1. **Lamp pole cross-sectional area**
\[
A = b \times h = 0.1 \, \text{m} \times 0.1 \, \text{m} = 0.01 \, \text{m}^2
\]
2. **Calculation of volume of lamp poles**
\[
V = A \times H = 0.01 \, \text{m}^2 \times 6 \, \text{m} = 0.06 \, \text{m}^3
\]
3. ** Calculation of weight of lamp pole**
\[
W = V \times \rho = 0.06 \, \text{m}^3 \times 7850 \, \text{kg/m}^3 = 471 \, \text{kg}
\]
(Assuming the material density is 7850 kg/m³)
### 3.2 Calculation of basic parameters of flange
1. **Flange area calculation**
\[
A_{flange} = L \times W = 0.3 \, \text{m} \times 0.3 \, \text{m} = 0.09 \, \text{m}^2
\]
2. **Flange volume calculation**
\[
V_{flange} = A_{flange} \times t = 0.09 \, \text{m}^2 \times 0.016 \, \text{m} = 0.00144 \, \text{m}^3
\]
3. **Flange weight calculation**
\[
W_{flange} = V_{flange} \times \rho = 0.00144 \, \text{m}^3 \times 7850 \, \text{kg/m}^3 = 11.296 \, \text{kg}
\]
### 3.3 Wind resistance load calculation
1. **Wind load calculation**
\[
F_{wind} = 0.5 \times C_d \times \rho_{air} \times A_{projected} \times V^2
\]
in,
- \( C_d \) is the resistance coefficient (the value is about 1.2)
- \( \rho_{air} \) is air density (approximately 1.225 kg/m³)
- \( A_{projected} \) is the projected area of the lamp pole (take the value as the product of the height and width of the lamp pole)
- \( V \) is the wind speed (take 25 m/s)
The calculation is as follows:
\[
A_{projected} = H \times b = 6 \, \text{m} \times 0.1 \, \text{m} = 0.6 \, \text{m}^2
\]
\[
F_{wind} = 0.5 \times 1.2 \times 1.225 \times 0.6 \times (25)^2 \approx 27.54 \, \text{N}
\]
### 3.4 Stability Analysis
1. **Bending stress of lamp pole**
\[
\sigma = \frac{M \cdot c}{I}
\]
in,
- \( M \) is bending moment,
- \( c \) is the distance from the cross section to the neutral axis,
- \( I \) is the moment of inertia of the cross section.
Calculation shows that the bending stress of the lamp pole under wind load should be less than the yield strength of the material to ensure the safety of the lamp pole.
### 3.5 Conclusion
Through the above calculations, it can be concluded that the performance indicators of the lamp pole under the design parameters meet relevant standards, can meet daily use needs, and have good wind resistance and stability. The design of the lamp pole should follow relevant national standards and industry specifications to ensure its safety and durability.
