The aim of this experiment is to be able to measure experimentally the natural frequency and the damping of an object, in this case a beam. The beam is subjected to bending and releasing, in which way the beam would oscillate. The movement of the beam is recorded using a pen connected to the free end of the beam, and the pen in contact with a chart recorder. The natural frequency is estimated by measuring the time interval between two successive peaks of the oscillations, then getting the reciprocal of this value. The damping is estimated by getting the Continue reading...
