A 5-kg uniform rod CD of length l = 0.7 m is welded at C to two elastic rods, which have fixed ends at A and B and are known to have a combined torsional spring constant K = 24 N · m/rad. Determine the period of small oscillations, if the equilibrium position of CD is (a) vertical as shown, (b) horizontal.
