Machine parts are the individual components that make up a machine, each serving a specific function. These parts can include items like gears, bearings, and motors, which work together to enable the machine to operate efficiently. Understanding the role of each part is essential for maintenance and repair. Different machines have unique sets of parts tailored to their specific tasks. For example, in a car, parts like the engine and transmission are crucial for movement, while in a computer, components like the CPU and motherboard are vital for processing information. Proper assembly and functioning of these parts ensure the machine performs as intended.
