Mechanical linkages are systems of interconnected components that transmit motion and force. They are commonly used in machines to convert rotational motion into linear motion or vice versa. Examples of mechanical linkages include levers, cranks, and cams, which help in various applications, from simple tools to complex machinery. These linkages can be designed in numerous configurations to achieve specific movements. By adjusting the lengths and angles of the components, engineers can create linkages that perform precise tasks, such as in robotic arms or automotive steering systems. Their versatility makes them essential in mechanical engineering.
