Here is the Navier-Stokes equation in Polar Coordinates & Spherical Coordinates (We have not covered this yet) Once we have to put out flow into these equations we would then integrate both sides to find the pressure and both put then together appropriately. Hamiltonian vs. Lagrange mechanics in Generalized Curvilinear Coordinates (GCC) (Unit 1 Ch. 12, Unit 2 Ch. 2-7, Unit 3 Ch. 1-3) Review of Lectures 9-11 procedures: Lagrange prefers Covariant g mn with Contravariant velocity Hamilton prefers Contravariant gmn with Covariant momentum p m Deriving Hamilton’s equations from Lagrange’s equations Application of the Euler-Lagrange equations to the Lagrangian L(qi;q_i) yields @L @qi d dt @L @q_i = 0 which are the Lagrange equations (one for each degree of freedom), which represent the equations of motion according to Hamilton’s principle. Note that they apply to any set of generalized coordinates For domains whose boundary comprises part of a circle, it is convenient to transform to polar coordinates. We consider Laplace's operator \( \Delta = abla^2 = \frac{\partial^2}{\partial x^2} + \frac{\partial^2}{\partial y^2} \) in polar coordinates \( x = r\,\cos \theta \) and \( y = r\,\sin \theta . exists that extremizes J, then usatis es the Euler{Lagrange equation. Such a uis known as a stationary function of the functional J. 2.

0 construction for the inertial cartesian coordinates, but it has the advantage of preserving the form of Lagrange’s equations for any set of generalized coordinates. As we did in section 1.3.3, we assume we have a set of generalized coor-dinates fq jg which parameterize all of coordinate space, so that each point may be described by the fq jg ﬁrst variation of the action to zero gives the Euler-Lagrange equations, d dt momentumz }| {pσ ∂L ∂q˙σ = forcez}|{Fσ ∂L ∂qσ. (6.4) Thus, we have the familiar ˙pσ = Fσ, also known as Newton’s second law. Note, however, that the {qσ} are generalized coordinates, so pσ may not have dimensions of momentum, nor Fσ of force.

2 r r ˙ φ ˙, Well, I would express the kinetic energy (T) in terms of polar coordinates as well as the potential energy (V). Then the Lagrangian L=T-V. Assuming you are dealing with the position and speed of one object, cylindrical coordinates make sense only if part or all of them can be varied independently of the others. And if those who can't, are fixed.
