... Answer: The tension is zero. By the same v v2 v1 argument as in the question above, one can show that the acceleration is straight down when the mass on the extreme right with the string horizontal. Since the acceleration is straight down, the net force must be straight down, so there can be no ...

... horizontal plane are related to θ by (x, y) = R sin θ(cos ωt, sin ωt), up to a phase. Since this relation involves t, the Hamiltonian is not the energy. But H is in fact conserved, because there is no t dependence in L. The Hamiltonian differs from the energy due to the minus sign in the second term ...
