Stress-Strain Apparatus without Sensors - AP-8221A
The Stress-Strain Apparatus lets students observe stress and strain as they stretch a material to the point of rupture. Add sensors to make quantitative measurements in real time.
Product Summary
This compact Stress-Strain Apparatus shows the stress and strain during the entire process of stretching and breaking a material. It offers a scaled-down version of traditionally expensive engineering devices, allowing students to explore all the same physics concepts without the high cost of a materials testing machine.
Since the Stress-Strain Apparatus shows the entire stress versus strain curve, it is possible to measure a wide range of material properties including:
- Young’s Modulus
- Yield strength
- Tensile strength
- Ductility
- Toughness
Students can also compare the different curve shapes produced by various materials.
PASCO Capstone software allows students to determine Young’s Modulus by measuring the slope of the initial straight line (the elastic region) and to determine the toughness by integrating under the curve.
