How Levers, Pulleys and Gears Work
The Efficient Engineer・2 minutes read
Mechanical advantage amplifies forces in systems like pulleys, levers, and gears, with the lever's mechanical advantage changing based on the fulcrum's position. Hydraulic systems utilize incompressible liquids to create mechanical advantage, and a CuriosityStream subscription offers access to detailed content on hydraulic systems and high-quality documentaries.

Recent questions
What is mechanical advantage?
Mechanical advantage refers to the ability of systems like pulleys, levers, and gears to amplify forces. It allows for the output force to be greater than the input force applied, making it easier to lift heavy objects or perform tasks that require strength.
How do pulleys work?
Pulleys work by redirecting forces, with a single pulley system requiring the same force as the load's weight. However, multiple pulleys can increase mechanical advantage by distributing the load over several ropes and pulleys, making it easier to lift heavy objects.
What are gears used for?
Gears are used to form gear trains that multiply forces in machines. The mechanical advantage of gears is determined by the ratio of teeth on the gears, allowing for precise control over speed and torque in various mechanical systems.
What are hydraulic systems?
Hydraulic systems utilize incompressible liquids, like in hydraulic presses, to create mechanical advantage. These systems are used in various applications where a high amount of force needs to be applied, such as in heavy machinery or automotive brakes.
What is CuriosityStream?
CuriosityStream is a platform that provides high-quality documentaries on various topics, including science, history, and technology. It offers a bundle deal with Nebula, a platform that offers exclusive content on hydraulic systems and other educational topics, providing a cost-effective way to access a wide range of documentaries and educational material.
