Exhibit Summary

Pull yourself is a Interactive interactive exhibit in the Mechanics in Motion category, designed for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Built as a hands-on, mechanical & electromechanical display, it turns an abstract scientific concept into direct, interactive visitor exploration, and is engineered for durable, low-maintenance, high-traffic gallery use.

Scientific Principle

The exhibition displays the concept of the compound pulley summarized by Hero, a technical engineer from the ancient Greek period, aiming to show that the technological inventions of that era still exert a wide influence today.

Operation

Hero analyzed and wrote the theory about compound pulleys, proving that the ratio of load to force is equal to the number of rope segments bearing the load, which is the "pulley concept". Pulley concept: When in use, the position of the pulley is fixed; the fixed pulley is essentially an equal-arm lever, which is effortless and effortless, but can change the direction of the force. The power arm and resistance arm of the lever are the radii of the pulley respectively. Since the radii are equal, the power arm is equal to the resistance arm, and the lever is neither labor-saving nor labor-intensive. Using the lever concept, the formula is derived (F is the pulling force, G is the gravity of the object, L1L2 is in the picture).
