9. WHEEL

Properties of Wheel and Spokes

1. Structural Integrity

• Wheels provide a strong structure to bear the load of the vehicle.
• Spokes distribute weight evenly, preventing the wheel from bending or collapsing.

2. Reduced Friction

• Wheels roll on surfaces, reducing friction compared to dragging or sliding.
• This efficiency allows for smoother movement and less energy expenditure.

3. Stability

• The circular shape of wheels provides a stable base, aiding balance.
• This stability is crucial for preventing accidents during transport.

4. Maneuverability

• Wheels allow for easy turning and direction change.
• This is essential for navigating various terrains and environments.

5. Versatility

• Wheels can be adapted for different vehicles, such as cars, bicycles, and trains.
• Various sizes and materials can be used to suit different transport needs.

Why Wheel is Preferred for Transport

1. Efficiency in Movement
   • Wheels enable vehicles to travel faster and with less effort compared to other modes of transport.
2. Energy Conservation
   • Using wheels conserves energy, making transportation more sustainable.
3. Ease of Construction
   • Reproducible design and materials make wheels easy to manufacture.
4. Increased Load Capacity
   • Wheels can support heavier loads without compromising structure.
5. Historical Significance
   • The invention of the wheel marked a significant advancement in human transport and has led to the development of modern transportation systems.

By providing these properties and advantages, wheels remain the preferred method of transport across various applications.
