4Piece Physics Experiment Pulley Set Package List 4 x experimental pulley block Key Features Purpose: Designed for handson mechanics experiments to demonstrate mechanical advantage, force distribution, and motion. Construction: Made from plastic and metal components for classroom use. Set composition: Includes two singlesheave pulleys and two doublesheave pulleys to create multiple pulley configurations. Sizes: Doublesheave pulleys: 11.00 x 4.00 x 2.20 cm (4.32 x 1.57 x 0.86 in) Singlesheave pulleys: 11.00 x 4.00 x 1.20 cm (4.32 x 1.57 x 0.47 in) Color: Green Operation: Simple design that is easy for students to assemble and use during experiments. Compatibility: Suitable for use with common classroom ropes, cords, and light wire as part of pulley demonstrations. Benefits Teaches core physics concepts through direct manipulation of pulley systems, helping students visualize how mechanical advantage changes with different arrangements. Adds flexibility to lab activities by offering both single and double sheave options for constructing block and tackle setups and comparative experiments. Streamlines classroom workflows with parts that are easy to set up, allowing more time for observation and analysis. Typical Applications Physics lab demonstrations: Build single, compound, and block and tackle systems to measure input and output forces and explore mechanical advantage. STEM projects and practical assessments: Use the pulleys in smallgroup experiments to test hypotheses about friction, load distribution, and pulley arrangement. Demonstrations of realworld principles: Model simple lifting systems or machine setups that relate textbook theory to practical examples.
