一种重要的机械装置

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.
