Explain a practical example where resonance is disadvantageous, and show how it can be avoided
Answers
Answer:
The disadvantages of resonance are as follows:
A negative effect of resonance could be the effect of waves hitting a rock face. The vibration of kinetic energy from the wave resonates through the rock face causing cracks and eventually great slabs of the cliff fall into the sea.
In a car crash a passenger may be injured because there chest is thrown hard against the seat belt. the vibration can burst blood vessels. Bruising of the skin or internal organs such as concussion of the brain can be caused because of the vibration of a movement.
If you are shot with a bullet the resonance of the bullet hitting the body can cause liquefaction of the internal organs, this can also occur if you are near a loud explosion. The vibration of the explosion will apparently burst blood vessels and liquefy some of the organs.
When bridge builders get it wrong and the wind causes it to resonate at its own frequency causing it to tear its self apart like the Tacoma Bridge in 1940.
Shattering glass when a high pitched sound is played.
