Metal Pulley Set for Physics Education A durable iron pulley set designed for handson physics experiments in school and home learning. Sturdy metal construction and precise wheel action deliver smooth, reliable operation for studying mechanics. Compact storage keeps components organized and ready for repeated use. Key benefits Durable construction: Iron pulleys resist wear and hold alignment for consistent, repeatable results during classroom or home experiments. Smooth performance: Wellmachined wheels reduce friction and allow accurate demonstrations of mechanical advantage, tension, and force. Ready to use: Includes straps and hooks for quick setup and easy adjustments between experiments. Organized storage: Supplied holder case reduces part loss and makes the set easy to transport and store. Educational value: Contains both fixed and movable pulleys for experiments that illustrate basic principles of pulley systems and mechanical advantage. What is included 2 double pulleys 2 single pulleys 2 straps 4 hooks 1 holder case Specifications Color: Black Material: Iron Larger pulley size: 12.00 x 4.00 x 1.00 cm (4.72 x 1.57 x 0.39 in) Smaller pulley size: 9.00 x 4.00 x 1.00 cm (3.54 x 1.57 x 0.39 in) Weight of larger pulley: 37.40 grams Suitable applications School physics lab: Demonstrate fixed versus movable pulleys, measure mechanical advantage, and compare input and output forces. Home learning and projects: Build small pulley assemblies to test principles of force, work, and energy in a handson setting. Teacher demonstrations and assessments: Set up quick experiments to show how pulley arrangements change required force and direction of motion. Notes on use Use the included straps and hooks to configure single, double, fixed, or movable pulley setups. The set is sized for middle school mechanics experiments but can be useful for basic demonstrations at other educational levels. Store components in the holder case after each session to prevent loss and keep parts organized. This metal pulley set provides a practical, long lasting kit for exploring fundamental mechanics with clear, repeatable results.
