TIANQIHAO Pointer Type Micro Deformation Demonstrator Optical Lever Object Tester Physics Principle Mechanics Teaching Instrument Classroom Lab Physical Experiment Equipment

TIANQIHAO

- Professional Physics Teaching Purpose: This elastic force demonstration instrument is a dedicated middle school physics experiment tool, specially designed for demonstrating the tiny deformation of objects and elastic force principles. It perfectly matches standard physics curriculum teaching requirements for intuitive mechanical principle explanation. - High-Precision Lever Amplification Structure: Featuring a secondary lever amplification mechanism with 7:1 and 8:1 lever arm ratios, this physics lab supply greatly amplifies tiny object deformation. A mere 1mm concave deformation creates a 50mm pointer rotation arc, delivering ultra-clear and visible experimental effects. - Intuitive Force Deformation Demonstration: Equipped with a precise scale plate and adjustable pointer, this physics teaching apparatus visually verifies the core physical rule: objects produce deformation under external force, and the deformation degree increases with force within the elastic limit through comparative weight tests. - Simple & Adjustable Operation: Designed with zero-point calibration screws and a stable bracket structure, this mechanics experiment device supports quick leveling and zero adjustment. Teachers and students can easily complete comparative deformation experiments with simple weight placement operations. Adopting exquisite structural craftsmanship with precision lever and pointer components, this educational physics instrument requires gentle handling and standard storage. It effectively avoids structural damage, supporting long-term repeated use for classroom demonstrations and laboratory teaching.
