Variable Pulley System

A variable pulley system adjusts the size of the pulley to change the mechanical advantage, enabling efficient transfer of power between components. By changing pulley diameters, it modifies the speed and force of the driven parts without needing additional gears. This system is common in applications like sewing machines, fitness equipment, or vehicle engines, where smooth control over movement and force is needed. It allows for seamless speed variation and flexibility by altering pulley ratios, making machinery more adaptable and efficient in performing different tasks.
