The horizontal platform shown between the spr:px+i( gr; y9yvkd(slings and the springs themselves have no mass. If the mass M is slightly displaced vertically, the mass exhibits simple harmonic oscillation. Assume that the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
