the amplitudes of the oscillation will build up and may lead to the destruction of the device or structure.
Another way to understand this is to hit a 2 by 4 with a sledge hammer.
Hit it again and again and you have the destructive force of the oscillation input by the blow from the hammer.
Stretch a rubber band between two points (like your fingers) and pluck it with another input force (like a finger) and it will cause waves of motion.
This is my opinion only
Vibration is a common thing in physics.
A force is needed to start or continue the vibration.
Some materials will vibrate once, and others will hold or store the input force for a longer period of time. Like a tuning fork.
This is the same as the swing of the pendulum. The vibration of the force applied to a pendulum will keel over time.
If the waves of force that has been applied in such a manner that they oppose each other, and the material is weaker than the time each wave stays in one place the material can brake down.
I would like opinions on this.
Where is this force as it is dissipated?
