    Hello ,

    i m looking for examples for simple harmonic motion,.. how does this theory apply in daily life?

    I had go through the net

    , i find that the examples given are the simple motion of the spring and pendulum. Any other examples on this?

    I would very appreciate on your reply as this will really help me in my understanding in oscilliations

    In the circuitous haze of my mind
    The resonant frequency of any object would be considered a harmonic motion. Also if you take a very long rope with someone holding the other end and shake it up and down you will form a harmonic motion as long as you move it consistently.

    Applications of this could be tuning a bridge so that any usage of it will not tune the resonant frequency and possibly damage it; tuning a car so that the bass frequencies are amplified; and adjusting the strength, flexibility and size of a spring in a jackhammer so that the piece returns in step every time.

    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.

    "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

    "Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence"

    A tuning fork, a guitar string, waves in a wave pool, a swing.

    An oscillating swing or pendulum is only approximately simple harmonic in motion. This is because in the mathematical derivation of its equation of motion, is approximated by (in radians). You only have for small values of .

    A spring will oscillate simple-harmonically provided Hooke’s law applies. In other words you stretch it so much that it goes out of shape.
