Question

The two springs, each of stiffness k=1.2 kN/m ,are of equal length and undeformed when theta=0 . If the mechanism is released from rest in the position theta=20,determine its angular velocity theta dot when theta=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.

The two springs, each of stiffness k = 1.2 kN/m, are of equal length and undeformed when theta = 0. If the mechanism is released from rest in the position 0 = 20 degree, determine its angular velocity (theta when theta = 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.
