Natural Frequency of a rod

    does the natural frequency of a steel rod rigidly fixed will vary when it is assembled with another rod by universal joint?

    Probably - but you will have to tell us much more about this problem before we can give you any definite answer .

    As a general rule, anything that affects stiffness will change the natural frequency.

    You say "rigidly fixed" which implies no gross motion, but you also speak of a universal joint which suggests large rotational motions. This is all pretty confusing, so a picture is essential here.
