    how to calculate sound speed in solid?
    I feel curious,why the sound speed in solid is related to the shear modulus of solid?
    why the sound speed is related to compressbility of matter?

    it is too hard to answer???
    nobody know the answer.....who is scientist and can help me to solve the problem?
    what factor causes the sound travel faster in air(which is gas) than in rubber(which is solid)?

    No it is not too hard to answer and you should be able to find the answer yourself.

    Go read a book. Or "google" the answer for yourself. Or even do the research to find the thread where this has been hashed out before.

    It is time for you to do some of the work yourself. I gave you a link and there are plenty of books on continuum mechanics that also can address your question.

    my question are not in the wikipedia...i ask:
    why shear modulus is related to mthe speed of longiudinal(sound) wave in solid?
    this is my question.wikipedia doesn't edcxplain this..i have search many website and not successful.so ,i come here to ask...can anybody help me??????
