It integrates lever, pulley and balance structure, equipped with precision dial and standard weights. Students can conduct hands-on experiments to intuitively explore lever equilibrium principle, torque, pulley transmission and other basic physics knowledge, turning abstract formulas into visible experimental phenomena. Ideal for classroom demonstration and home science learning, cultivate scientific inquiry thinking and practical ability.\u003c\/p\u003e\n\u003cp\u003e✅ 3-in-1 design with lever, pulley and balance, learn multiple mechanics knowledge at one set\u003c\/p\u003e\n\u003cp\u003e✅ Clear precise scale with standard weights for accurate experiment measurement\u003c\/p\u003e\n\u003cp\u003e✅ Transparent acrylic stand, visible structure to easily observe mechanical movement\u003c\/p\u003e\n\u003cp\u003e✅ Safe and durable material, stable base to prevent tipping during experiments\u003c\/p\u003e\n\u003cp\u003e✅ Supporting teaching aid for middle school physics, for learning torque and lever balance\u003c\/p\u003e\n\u003cp\u003e✅ Hands-on inquiry learning, avoid rote memorization and inspire interest in physics\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplicable Age\u003c\/td\u003e\n\u003ctd\u003e12+ Years Old\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePlastic + Acrylic + Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePhysics Mechanics Experiment Teaching Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eLever Principle, Torque \u0026amp; Pulley Mechanics Learning\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Include\u003c\/td\u003e\n\u003ctd\u003eMain Machine, Standard Weights, Measuring Scale, Dial Plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eContains small metal weights.
