a sheep with a mass of 50 kg is hung on an animal scale system which consists of a helical spring of negligible mass. The stiffness (k) of the spring is 60 kN/m. During the hanging operation, the spring and the sheep are displaced vertically by 20 mm below the equilibrium position. draw a free body diagram and prove that the total length (L) of the scale system can be expressed as : L= (2mg/k) + L0, where L0 is the unstretched length of the spring. also determine the frequency of natural vibration of the system.
