Vibration
University: University of California, Santa Barbara Strain gages and accelerometers are sensors frequently used in mechanical measurements. This experiment provides an introduction to their use for dynamic measurements, such as measurements in which the observed quantities vary rapidly with time. Students monitor the oscillation of the cantilever beam with an accelerometer mounted at the tip of the beam and a pair of strain gages bonded to the beam at a point near its base. They examine issues related to the properties of the sensors, the electrical circuitry needed to condition their output, and the effects of various factors, such as temperature, on the measurements. |
