If a strain gage or accelerometer were attached to the beam it would generate a sinusoidal voltage output. The output amplitude would be proportional to the strain or acceleration and a period inversely proportional to the frequency of vibration. Left to vibrate freely, without applied external forces, the beam will vibrate at its.
