4. DATA ANALYSIS AND DISCUSSIONS
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; determine elastic modulus of a cantilever;
compare measurements with analytical and/or computational models.
Conduct uncertainty analysis on the results. Assume 3% of uncertainty in strain
measurements. Refer to provided sample uncertainty analysis.
Identify, in order of importance, percentage contribution of all uncertainties to the overall
uncertainty in pressure characterizations and Poisson’s ratio measurements.
*For optional activities during this laboratory, refer to Document 4.
