Mechanical transmission refers to the process of transferring power and motion from one component to another within a machine. This is commonly achieved through various mechanical elements such as gears, belts, chains, and pulleys. These components work together to convert the energy produced by a motor or engine into useful work, enabling machines to perform specific tasks. In many applications, mechanical transmission systems are essential for controlling speed, torque, and direction of movement. For example, in vehicles, the transmission system allows the engine to efficiently transfer power to the wheels, facilitating smooth acceleration and deceleration.
