Calculate the damping coefficients for each of the cantilever systems. Calculate the natural frequency using the data from the accelerometer test. On the same graph, plot the theoretical natural frequency vs. mass curve for the cantilever beam system and all of the experimental data points. Compare the various measures of natural frequency. Discuss the type of damping that is present in the cantilever.
Leveling is important to keep the rod from striking the table or rubbing against the housing.
To level, adjust the feet on the bottom of the analyzer. Reset the zero phase reference before each new test. Allow the system to come to a steady state before recording any data. For all test record the following parameters. A f - forcing amplitude, which is determined by reading the scale on the back of the machine.
