- Axle: The axle is typically made of steel, due to its strength and durability.
- Wheel: The wheel can be made from various materials, such as wood, metal, rubber, or plastic. The choice of material depends on the intended use and weight load.
>- Wood: Wooden wheels are commonly used in traditional or antique carts, wagons, and other simple mechanisms.
- Metal: Metal wheels, typically made of steel or aluminum, are frequently employed in industrial machinery, farm equipment, and vehicles due to their strength and durability.
>- Rubber or Plastic: Rubber or plastic wheels are widely used in vehicles and toys, as they provide good shock absorption, traction, and durability.
- Bearings: Bearings are essential components placed between the axle and the rotating parts to reduce friction and facilitate smooth rotation. They are often made of metal, such as steel, and are designed to withstand the forces and stresses applied during rotation.
- Lubricants: Lubricants are used to further reduce friction between the axle and bearings, enhancing the efficiency of the wheel and axle system. Common lubricants include oil and grease.
The selection of materials for Wheel and Axle depends on various factors such as the load, speed, and environment in which the system will operate.
