A chassis is the framework or structure of a vehicle, providing support for various components such as the engine, wheels, and body. It is essential for maintaining the vehicle's shape and stability while allowing for the attachment of other parts. The chassis can be made from materials like steel, aluminum, or composite materials, depending on the vehicle's design and purpose. In addition to vehicles, the term chassis can also apply to other machines and equipment, such as computers and electronic devices. In these contexts, the chassis serves as the base that houses and supports internal components, ensuring proper functionality and protection from external elements.
