    Hi teacher, thank you for solution. I have a request. Can you share where did you find from questions at your classic mechanics list? I could not find those kind of questions.

      Same

      You need to do a course that includes Lagrangian Mechanics (first year uni). Any average uiversity Classical Mechanics textbook should have a chapter on Lagrangian Mechanics. There are plenty of these questions over there.

    I have an exercise which asks the constraint force, the answer is F = -[mg/[1-(m+M/m)*tan^2(theta)]]. Using the constraint that you used I found a similar answer but isn't the same, do you know how I can get to that answer?

      Hi. Yes it is very similar to the result here. But are you sure the coordinates (x-y axes) are defined same as here in this video?

      @@physhell9926 No, i'm not sure because the exercise doesn't show any figure.

      But a thing that caught my eye is the fact that you choose as your generalized coordinate diferents coordinates that if you were solving the same problem without considering any constraint.

      and that answer one question that I had: "If I try to solve it using the multipliers and then don't using them, do I have to choose the same generalized coordinates in both cases?"

    You could have done it without the lambda, no?

    • @jesusk1358
      @jesusk1358 Місяць тому

      Yes you can. But this is the complete method. Without this lamba, you can calculate the accelerations but you won't have a clue about the forces of constraints.
