06.49: Three identical Hookian springs of
jl ao2x l9n;7fspring constant k are connected as shown to a mass M in equilibrium. The horizontal platform shown between the springs 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 d
x7ofj nl;92l aoes not rotate during the oscillations.What is the period of the oscillation?
