It was found that viībration improves or contributes also to the effciency of certain industrial processes. 3. If the system is damped, some energy is stored in each cycle of vibration and must be replaced by an external source if a state of steady vibration is to be maintained. 4. Basically, the oscillation of a pendulum would naturally stop due to the resistance offered by the gravity. 5. The work done in deforming a spring is stored as strain or potential energy is represented by the area of a triangle. 6. In an octave band, it can be…
