Measure force and displacement for various materials as they are stretched, compressed, sheared, or bent. Investigate material properties including Young’s Modulus, Tensile Strength, Yield Strength, Ductility and Modulus of Resilience.
The Materials Testing Machine measures force with a 7100 N load cell and displacement with an optical encoder. It runs on PASCO Capstone software, which has a built-in compliance calibration wizard and has all the tools to record and display stress vs. strain, apply linear fits to find Young’s Modulus, and to record and play back webcam movies of the breaking samples, synced to the data.
Workbooks include all instructions needed to perform the experiment:
- Introduction and theory
- Setup instructions
- Detailed analysis and summary questions
