Answer» Four identical rods of mass $M = 6 kg$ each are welded at their ends to form a square and then welded to a massive ring having mass $M = 4 kg$ and radius $R = 1 m$ . If the system is allowed to roll down the incline of inclination $θ = 30^{\circ}$ . The minimum value of friction coefficient to prevent slipping is
