Strain Gage

This lab explores the concept of strain measurement using a strain gage. Students will take measurements from and calibrate a strain gage mounted on a cantilever beam and placed in a quarter-bridge Wheatstone configuration. Then they will measure the natural frequency of the beam assembly by applying a fast Fourier transform to the response of the beam due to an impulse.
