This paper theoretically and experimentally examines the weakly nonlinear oscillations of a multi-degree-of-freedom dynamical system with internal resonance. The analytical model is sustained by the linear springs which have angle. The natural frequencies (ω_z, ω_y, ω_θ) are controlled by changing the angle of the springs. This model can have the case with internal resonance and nonresonance. For each case, Nonlinear Normal Modes were derived by me method of Vakakis, and they were compared with Nonlinear Normal Modes, which is obtained by the method of Shaw and Nayfeh. The advantage of using Nonlinear Normal Modes is that it enables one to analyze a natural mode ofvibration.
