Color: Multix5pcs; Size: 10.00X4.00X2.00CMx5pcs Overview A set of five single pulley blocks with hooks, designed for classroom and handson experiments. Each unit combines a plastic body with an iron hook and axle to provide durable, safe, and easytouse components for exploring pulley mechanics. Key benefits Practical learning tool for mechanics: Enables students to observe and measure fundamental pulley principles such as direction change of force, mechanical advantage, and friction in real time. Ready to use and easy to mount: Builtin hooks make it simple to hang the pulley from beams, stands, or rigs, speeding setup and reducing downtime in labs and workshops. Durable construction for repeated use: Plastic housing and iron hardware provide strength for routine educational experiments while keeping units lightweight and portable. Consistent performance: Smoothrolling pulley wheel minimizes binding so demonstrations remain clear and repeatable. Product features Pack contains five pulleys in multicolor format for easy group distribution and identification. Single pulley block design for straightforward experiments and demonstrations. Dimensions per unit: 10.00X4.00X2.00CM, compact size suitable for desktop and bench setups. Materials: plastic body with iron hook and axle components. Hooked mounting point for quick attachment to stands, clamps, or improvised supports. Why you need it This set simplifies handson study of mechanical systems by providing reliable, uniform pulleys that are easy to use and quick to integrate into curricula. They help reduce setup complexity so instructors can focus on core concepts and guided experimentation rather than hardware troubleshooting. Suggested use scenarios Classroom physics lab: Use individual pulleys to demonstrate single fixed pulley behavior, compare single and compound pulley arrangements, and let students measure input versus output forces. STEM projects and workshops: Integrate pulleys into small machine builds, robotics prototypes, or pulley and lever experiments to illustrate realworld mechanical applications. Home or club experiments: Ideal for group activities where each participant needs an identical pulley for measuring tension, testing friction, or constructing simple lifting systems. Compatibility and handling Compatible with standard lab stands, clamps, and lightweight rigs that accept hookmounted hardware. Compact and lightweight for storage and transport; suitable for student use with appropriate supervision. Clean with a dry cloth; avoid submerging in liquids to preserve the iron components. What makes it stand out Pack of five identical pulleys in multicolor format supports group learning and clear identification. Solid combination of plastic and iron balances durability and ease of handling for repeated educational use. Designed specifically for handson exploration of pulley mechanics, helping students develop practical understanding of force and motion. Included in the package Five single pulley blocks with hooks, each sized 10.00X4.00X2.00CM.
