Mechanical linkage refers to a system of interconnected components that transmit motion and force from one part to another. These linkages can convert rotational motion into linear motion or vice versa, allowing machines to perform various tasks. Common examples include levers, gears, and crankshafts. Linkages are essential in many mechanical devices, such as automobiles, robotic arms, and industrial machinery. By using different configurations, engineers can design linkages to achieve specific movements, enhancing the efficiency and functionality of machines. Understanding mechanical linkages is crucial for fields like mechanical engineering and robotics.
