A wheel is a circular component that rotates around an axle, allowing for movement or transportation by reducing friction.
A wheel typically consists of a circular rim, a central hub, and spokes connecting the rim to the hub. The rim may be solid or hollow, and it usually has an outer surface designed to attach a tire for traction and shock absorption. The hub is the central part of the wheel where it attaches to an axle.
Wheels serve the primary function of enabling smooth and efficient movement across surfaces. When attached to an axle, wheels can rotate freely, allowing vehicles, machinery, or other objects to roll along the ground with minimal resistance.
a wheel is a fundamental mechanical component that enables movement by rotating around an axle. Its versatility and widespread use make it an essential feature in various industries, transportation systems, and everyday activities.
