Abstract:
We wanted to study the vibration of a beam fixed at one end and free
at the other. Specifically, we wanted to find the damping factors for the
first four modes of vibration as well as experimentally determine the location
of the nodes for the first four modes of vibration. Damping factors are
unique to a particular mode of vibration. The extent to which a particular
frequency of vibration is excited depends on the location at which the
beam was struck, ie. if the node of a particular frequency is struck, the
beam will not vibrate at that frequency. Equation 2 accurately predicts
5 out of the 6 nodes in the first four natural frequencies of vibration.
