عجلة

Also known as wheels

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.

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.

العجلة جهاز دائري يمكنه الدوران حول محوره، بحيث يسهل الحركة أو النقل أو أداء الشغل في الآلات. تتغلب العجلة على الاحتكاك بالأرض بتسهيل الحركة عن طريق التدحرج. تستخدم الكلمة بشكل أعم للتعبير عن الأجسام الدائرية الأخرى التي تدور أو تلف.
