    I believe the first resultant equation's end should be -kx, shouldn't it?

    in equation (2) two terms cancel out because of same value but opposites in sign ... and BTW excellent way of teaching thanks

    You had a sign mistake in the second equation (for pendulum). Some terms could have been canceled at there!

    Hello Rhett,
    I highly appreciate your work, It is really helpful.
    I have a technical question, if the whole system rotate around Z-axis, how can I update the equations of motion.
    If you have a reference that it might help. I would be really grateful.
    Thank you

    the pause at 9:57 is awesome

    what if we had an other pendulum atteched to the first one :/ HOW CAN WE FIND THE LAGRANDE ? I DID IT BUT IT WASS SO LONG

    Nice explanation, but I get stuck with The natural frequency of the systems

    Can someone tag me on a problem like this one solved in a book ? I am searching but I can not find an equation of motion solution of this kind of problem..

    you dropped the 2 in the original equation for T in the part 2*L*X_dot*Theta_dot*cosTheta

    Why is it that your potential for the pendulum is not mgL(1-cos(theta))?

      guess he has made a mistake there. should be mgl(1-cos (theta)).

      IT IS CORRECT, U=0 at y2=0 , x=0 .
      -m2*g*L(1-cos(theta)) when U=0 at y2=-L , x=0 .
