Free Vibration, 1DOF, Walkthrough?

[Jowin86]

Hi,

I've just started a degree in Mechanical Engineering after a HNC and I am having trouble with the Dynamics module!

The lecturer literally just blabbed on about Free Vibration and did a worked example of a free vibration system with 1 degree of freedom. He didn't tell us any of the equations used or what any of the symbol stood for and i learned nothing.

I've read around for a few hours and got most of the x=displacement, m=mass, omega(n)= natural frequency but i need some worked examples that I can work through in order to get used to working out the questions etc.

So basically my questions is does anyone know of any online worked examples that I can try and figure this out with?

Thanks in advance for any help, I am guessing I've not made a lot of sense here so any help is much appreciated!

Hi there,

I completely understand your frustration with the Dynamics module. It can be a challenging subject, especially when the lecturer doesn't provide enough information or examples.

First of all, it's great that you have already identified some of the key equations and symbols used in free vibration. This shows that you are on the right track. However, it's important to have a solid understanding of the underlying principles and concepts before attempting to solve specific examples. This will help you tackle a variety of problems and not just the ones you have seen before.

I would suggest looking for resources online such as video tutorials or practice problems with solutions. Some good websites to check out are Khan Academy, MIT OpenCourseWare, and Coursera. You can also try searching for specific topics on YouTube, as there are many channels dedicated to engineering tutorials.

Another helpful tip is to reach out to your classmates or join a study group. Collaborating with others can often make difficult concepts easier to understand. You can also ask your lecturer or teaching assistant for additional resources or clarification on any confusing topics.

Remember, practice makes perfect. So don't be afraid to work through as many examples as you can find. And if you still have trouble, don't hesitate to seek help from your lecturer or a tutor. Good luck with your studies!
