This paper presents a simple experimental approach that can be used to evaluate lowerorder harmonic frequencies of a flexible beam. The beam was simply excited by a tap at a specific point, and the beam vibration was detected by a piezoelectric accelerometer. The vibration data was acquired and analyzed in the frequency domain. With proper choices of sampling frequency and the locations of the sensor, the frequency modes of a flexible beam can be estimated via frequency domain analysis.
