Mechanical Vibrations 14 - Lagrange 2 - Conservative systems (Examples) 

thanks a lot, these videos are really helpful!

we love this guy

clear explanation, thanks a lot

can you explain more the chain rule of calculus in this case please?

What a beautiful writing

What is x… you don’t define? Also what is the difference between x1 and x2?

If the masses and sping constants are same in 1st problem, how the expression of kinetic and potential energy will vary? Please answer

Thank you so much !!!

Life saver

Thanks a lot Sir.

thank you

FOR LAGRANGE eq the system must be holonomic i.e Number of Degrees of freedom should be equal to the number of coordinates. How many degree of freedom does this system have?

Thank you
