The effects of radial clearance, viscosity of the lubricating oil, and inlet pressure, on the oil whip phenomena of flexible rotors were studied experimentally. The observations are compared with the stability zones that can be predicted by Morrison's stability charts.
In this study, we derive a finite difference for a Timoshenko beam with boundary feedback by the method of reduction of order on uniform meshes. It is proved by the discrete energy method that the scheme is uniquely solvable, unconditionally stable and second order convergent in L∞L∞ norm. Numerical results demonstrate the theoretical results.
An algorithm for deriving a continued fraction that corresponds to two series expansions simultaneously, when there are zero coefficients in one Nike Air Max or both series, is given. It is based on using the Q-D algorithm to derive the Nike Air Max 2010 Canada
corresponding fraction for two related series, and then transforming it into the required continued fraction. Two examples are given.
The various stages in the mathematical modelling of real problems are first discussed briefly and then illustrated stepwise with the problem of cutting a die for the lenses of automobile stoplights. This requires the determination of the shape of a groove cut into a rotating metal blank as a function of the shape of a cross-section of a rotating cutting tool.
