ABSTRACT
In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen. The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency. The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.
