| Abstract: | The differential equation of motion of the system with two degrees of freedom is formed by use of Lagrange's equation, and the movement of the system is given by the numerical solution carried out by computer. It shows that the effect of the force of friction cannot be omitted when the system moves near the equilibrium position. |
