Introduction
Rigid materials, when subjected to specific stresses or forces, can undergo deformation—whether compressed, twisted, or stretched. For many materials, the restoring force that resists deformation and returns the material to its original shape is directly proportional to the extent of deformation. This relationship is defined by Young's Modulus (E), a constant that quantifies a material's stiffness, expressed as the ratio of stress to strain during tensile or compressive stress.
The LEMI-12 Young's Modulus Apparatus is designed to investigate the deformation behavior of thin metal sheets under applied loads. The apparatus applies a small force (F) to the sheet, causing measurable deformation. A Hall-effect micro-displacement sensor precisely tracks this deformation, providing an output voltage directly proportional to the displacement.
With this apparatus, users can explore foundational principles and perform hands-on experiments, including:
1. Gaining insights into the principles, structure, properties, and applications of Hall-effect displacement sensors
2. Measuring the Young's Modulus of a copper specimen
3. Calibrating the Hall displacement sensor for accurate measurements
4. Determining the Young's Modulus of a malleable iron specimen
The included instruction manual offers everything you need for a successful lab experience:
- Clear explanations of principles
- Step-by-step procedural guides
- Sample experimental results for reference
