Rigid Body Lagrangians

  1. Oct 25, 2008 #1
    1. The problem statement, all variables and given/known data

    two particles, [tex]m_{1}[/tex], and [tex]m_{2}[/tex] are connected together by a thin masses rod of length d. The system moves under a uniform potential function [tex]U(r_{1}^{\rightarrow}, r_{2}^{\rightarrow})[/tex].

    What is the Kinetic energy of the system in cartesian coordinates?

    2. Relevant equations

    The constraint equation we were given:

    [tex]f(r_{1}^{\rightarrow}, r_{2}^{\rightarrow}) = |r_{1}^{\rightarrow}, r_{2}^{\rightarrow}| = d [/tex]​

    3. The attempt at a solution

    I am not sure how to approach the problem, any hints on how I can start this would be great!
