"Ever wondered how an electric fan swings smoothly from side to side? Inside the fan, a clever four-bar linkage mechanism makes it possible. In this animation, you’ll see how the yellow connecting rod drives the motion, while the pink bar and the fan housing act as rockers. Together, they transform continuous rotation from the motor into a smooth oscillating movement. This simple yet smart mechanism ensures steady airflow across the room. 🔧 Mechanical design at its finest!" | Breno Cruz
