Resonance

Welcome again my dear friends,this post is about those who changes their mind/decisions very frequently.If we express the mental status of this kind of peoples,then it will resemble the graph of alternating current which you can see in attached picture.If we talk about ac/simple harmonic motion,one phenomena comes in our mind that is RESONANCE.In physics, resonance is the tendency of a system to oscillate at a greater amplitude at some frequencies than at others. These are known as the system's resonant frequencies). At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy.If you understand resonance then it is very easy to feel my this post and if not then no problem i will try to explain.You see when something vibrates, the objects surrounding this will also vibrates but in different frequency.If the natural frequency of the original object differs from the frequency of surrounding objects,then it is not very much dangerous but what will happen when the frequenies becomes equal(at resonant frequency) ?The is answer is depicted in the attached picture.You can see the amplitude of vibrating object is maximized,which is very dangerous.For example any nut-bolt/screw of your motorcycle/scooty is loose then it can open any time when you are driving your automobile and will cause accident.So my friends any frequently changing thing can be dangerous any time.My friends beware from this kind of people.I need your essential comments.OK bye and see you soon.
