Does Assembling a Steel Rod with a Universal Joint Affect Its Natural Frequency?

[HARIKRISHNAN KR]

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

 

[Nidum]

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

 

[Mech_Engineer]

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.
