06.49: Three identical Hookian springs of spring constant k are
g0+ a/ ypoo0jp connected as shown to a mass M in equilibrium. The horizontal platform shown between the springs and the springs themselves have
/pag0poj0oy + 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?
