Sentence examples for cases of friction from inspiring English sources
Several cases of friction, zero moment point location, and the center of mass height variation are considered in the study.
However, the problem arises when the system has atomic fabric of matter such as in the case of friction problems and phase-change problems of fluid freezing into a solid or dynamic transition such as intermittent stick-slip motion [40].
Contemporary equipment was not very portable, and in the case of friction machines required skilled operators to keep going.
In the second part we present a finite element model of a 3D bolted joint taking into account two types of non-linearity (unilateral contact and friction model) in which we show the risk of loss of rigidity in the case of inadequate friction force.
Numerical results from the interaction model confirm that stick/slip oscillations occur also in the case of constant friction.
In the case of nonmonotonic friction law the stick-slip vibrations can occur even under the action of constant external forces.
The case of constant friction coefficient ratios is re-examined leading to a screening of the existing theories for multi-component polymer systems.
Most authors introduce the negative slope of the friction characteristic as a source of the instability, while others have found that squeal can also occur in the case of constant friction due to the coupling between normal and tangential dynamics.
As a contribution to this discussion, a detailed model for high-frequency wheel/rail interaction during curving is presented in this paper and evaluated in the case of constant friction.
In this case, the influence of friction on the manipulator motions is such that dynamic modeling, identification and control, are no longer adapted, nor even possible.
In this case, the use of friction connections in steel towers enhances the possibility of dismantling and reusing the tower potentiating much better performance in relation to the environmental category of global warming.
