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

AI Thread Summary
Assembling a steel rod with a universal joint likely affects its natural frequency due to changes in stiffness. The discussion emphasizes the need for more detailed information to provide a definitive answer. The term "rigidly fixed" suggests minimal gross motion, yet the inclusion of a universal joint implies potential for significant rotational movement. This contradiction creates confusion, highlighting the importance of visual aids, such as diagrams or pictures, to clarify the setup. Overall, understanding the interaction between the components is crucial for assessing the impact on natural frequency.

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.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
