A wood cantilever of length ~2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and…
