Strain and Force

In this lab, students will implement strain and force measurements using a strain gauge and a load cell. They will experiment with different resistive measurements: quarter bridges and full bridges. Finally, they will implement their own measurement system to solve a measurement problem using the sensors and tools they’ve learned about.

This is lab 14 of 17 in the course, Measurements and Instrumentation.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Implement a metal film strain gauge in a quarter-bridge setup
  2. Learn about half-brdge & full-bridge setups
  3. Assess the effect of increasing resistance of the resistive sensor within a bridge configuration
  4. Use a load cell to measure force
  5. Calibrate a force measurement using either known weights or multiple identical items
  6. Design and implement a measurement system to solve a force-based measurement challenge
