A two-degree-of-freedom system, in which rolling oscillations are forced, is described. Details of the system, the theory, and the method of operation are discussed. It is shown that, although the system is characterized by nonlinear equations of motion, linearization of the equations by assuming small perturbations and constant coefficients yields sufficiently accurate results.
