A wheel is a fundamental mechanical component designed to rotate around an axis, enabling motion with minimal friction. It consists of a circular rim connected to a central hub by spokes or a solid disc, often paired with an axle for support. Wheels are essential in transportation, allowing vehicles like cars, bicycles, and carts to move efficiently. They also play a crucial role in machinery, enhancing functionality in gears, pulleys, and other rotating systems. Modern wheels can be made from materials such as metal, plastic, or composite alloys, tailored for durability and performance. Beyond mechanics, wheels symbolize progress, movement, and innovation. Their invention revolutionized human civilization, transforming travel, trade, and industry by simplifying the movement of goods and people.
