Homework Statement
Hello. I have this problem:
I have a ring which is sliding along a wire in the shape of a spiral because of gravity.
Spiral (helix) is given as the intersection of two surfaces: x = a*cos(kz), y = a*sin(kz). The gravity field has the z axis direction.
I have to find motion equations and find the wire reaction as a function of time.
2. Homework Equations
I have to solve it with this equation:
The Attempt at a Solution
This is the first time, when I solve a example with Lagrangian equations, so I am not sure what to do.
I created this equations:
I know, it is not the end. I have to find λ, motion equations and the wire reaction. But firstly, please, tell me, if I am right or where is mistake and why. Then I will continue.
Thank you very much.
