Description
Purpose of the Experiment
The purpose of the vibration measurement experiment is to use strain gauges to measure
the dynamic characteristic and the elastic material properties of cantilevers. Vibration data will
be analyzed to:
 Determine the vibration amplitude, velocity, and acceleration in various units of measure;
 Determine natural frequencies;
 Measure and express damping characteristics as logarithmic decrement and percentage of
critical damping;
 Compare measurements with analytical and/or computational models of a cantilever; and
 Determine elastic modulus of a cantilever
