06.49: Three identical Hookian springs of spring constant k a
5 l 2k1udu9 l+l.xss a/lj9otzre connected as shown to a mass M in equilibrium.
1x/sua 9 jolt+29zds 5kl lul.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 does not rotate during the oscillations.What is the period of the oscillation?
