Simple Machines
Learning Time: 4-12 hours
Content: Simple machines are devices that change force, distance, or direction to facilitate work. This topic covers levers, pulleys, inclined planes, screw and pulley systems, mechanical advantage, efficiency, and practical applications. The TYT focuses on basic machines and advantage, while the AYT focuses on efficiency analysis and complex combinations. The current 2025 curriculum also covers automation and renewable energy machines. Learning this topic forms the foundation for engineering and technological design.
