What is the sign convention? When is a term xa*kb counted positive, when negative? For example, when m1 moves in direction x1 it stretches k1 and compresses k2 but both x1k1 and x1k2 are counted positive.
I have been looking for your next video, but haven't found it yet. Please let me know if you've uploaded it, or plan to upload it soon. I need to know how to find the natural frequencies from equations of motion.
Hi Vimal. Thanks. You have shared a great video. That would be my video as well apart from this one. That is why I put 'A Quick way' in the title. The one explaining the free body diagram should be a more appropriate one to explain the physics. But still can't find time to put my voice-over on my video:)
Very good video , could you make more of it pls 🎉
Thanks from India

Will do!
please upload the next step for eigenvenctor mode shapes untill finish
Thank you
i cant find the next video
A free body diagram analysis of each mass would have been a lot easier to understand

Is k3 not considered in the equation of motion for m1 because k3 compresses?
k3 is not attached to m1. Basically, all forces acting on mass are from the element attach to it.
How to rearrange these motion equations?
Just follow the steps in the video. You will have two equations of motion.
