The term "chassis" refers to the framework or structure of a vehicle, such as a car or truck. It serves as the base that supports various components, including the engine, wheels, and body. The chassis is crucial for the vehicle's stability and performance, as it holds everything together and allows for safe movement. In addition to vehicles, the concept of a chassis can also apply to other machines and devices, like computers and electronics. In these cases, the chassis provides a protective casing and support for internal parts, ensuring they function properly and remain secure during use.
