The 12-kg block is supported by the two 5-kg links with two torsion springs, each of constant k_T = 500 N ∙ m/rad, arranged as shown. The springs are sufficiently stiff so that stable equilibrium is established in the position shown. Determine the natural frequency ƒ_n for small oscillations about this equilibrium position.
