06.49: Three identical Hookian springs
8 cp)dsb 3w8u knu+1gf of spring constant k are connected as shown to a mass M in equilibrium. The horizontal platform shown between the springs
1u 8w3)gufd+cbnp 8ks 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?
