wheel
Sign in to saveA wheel is a rotating component (typically circular in shape) intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle, which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily, facilitating transportation, supporting loads, and performing work in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
AI overview
A wheel is a circular object that spins around a shaft called an axle, and it's one of the six basic simple machines that humans use to accomplish work. Wheels are essential because they make it much easier to transport heavy objects and power machines, and they serve many other purposes like steering vehicles and powering equipment.

A wheel is a rotating component (typically circular in shape) intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle, which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily, facilitating transportation, supporting loads, and performing work in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
Common examples can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. For a wheel to rotate, a moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque.
