Consider 2 rings, both of mass m, that slide without friction along 2 bars, arranged as shown in the figure, forming an angle 2α between them. The rings are joined together by a spring with an elastic constant. k. At the initial instant, the compression of the spring is d and the rings are at rest at a height h above the vertex formed by the two bars. When the system is released, the rings begin to climb the bars.

 

a) Show that the system performs simple harmonic motion. Which the equilibrium position?

b) Determine the angular frequency and the period of oscillation of the described MAS.
