Question
The image is a table used to calculate the maximum contact pressure for wheels of varying materials and dimensions on a rail.

| d   | w    | F     | Wheel Material | Rail Material |
|-----|------|-------|----------------|---------------|
| 3 in | 1.25 in | 250 lbf | Cast Iron     | Cast Iron    |
| 150 mm | 40 mm | 2 kN   | Steel         | Steel        |
| 5 in | 2 in | 600 lbf | Steel         | Cast Iron    |

- **d**: Diameter of the wheel
- **w**: Width of the wheel
- **F**: Load on the wheel (force)
- **Wheel Material**: Material of the wheel (Cast Iron or Steel)
- **Rail Material**: Material of the rail (Cast Iron or Steel)

This table provides data needed to estimate maximum contact pressure for different combinations of wheel and rail materials.
