Abstract : The effect of gravity as a simple vertical body force was included in the steady state pressure distribution of a rapidly spinning liquid. For the simple case of a completely filled cylinder, the classical liquid-filled gyroscope stability problem was considered. Analysis showed that the liquid eigenfrequencies were identical to the Stewartson case and that a new, but second order, liquid moment term resulted. (Author)
