Mechanical components are the individual parts that make up machines and mechanical systems. These components can include items like gears, bearings, and shafts, which work together to perform specific functions. Each part plays a crucial role in ensuring that the machine operates smoothly and efficiently. In many applications, mechanical components are designed to withstand various forces and stresses. For example, gears transmit power and motion, while bearings reduce friction between moving parts. Understanding these components is essential for engineers and technicians who design and maintain machinery in industries such as automotive, aerospace, and manufacturing.
