The two springs, each of stiffness k = 1.2 kN/m, are of equal length and undeformed when θ = 0. If the mechanism is released from rest in the position θ = 20°, determine its angular velocity when θ = 0. The mass m of each sphere is 3 kg. Treat the spheres as particles and neglect the masses of the light rods and springs.
