1. Devastating effects of vibration occurs when the natural frequency of a certain structure coincides with the internal excitation. _ 2. It was found that vibration improves or contributes also to the efficiency 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 observed that the minimum value of a range of frequency is half of its maximum value.
