Motion in a Central Force Field - Equations One of the most widely used coordinate methods to represent particle motion under a central force is through the application of a polar coordinate system. If the central force is represented in the r direction, the equation can be defined as: \[F=...
In the membrane theory of shells there are one moment and three force equilibrium equations. For shells of revolution, force equilibrium in a meridional plane may be expressed in the radial and axial directions or in the tangential and normal directions. An observation by Reissner suggests six ...
Coulomb force and dielectric force belonging to the body force of different electrolytes in the microchannel were analyzed. The force criterion at the interface was concluded, and testified by the specific example. Three basic equations were analyzed and applied to simulate the phenomenon. The force ...
3.1 The basic field equations in F(Q,T)-gravity for wormhole geometry We take into account the symmetric teleparallel gravity action put out by Xu et al. [13] SG=∫[F(Q,T)16π+Lm]−gd4x. (2) In this scenario, F(Q,T) is a function of the non-metricity of Q and the trac...
These curves have an anomalous shape for a chain of two rods. End-to-end distributions of rod-coil chains are calculated by Monte Carlo method and compared with analytical equations. The influence of the spacer's length on the force-extension curves in different probe methods is analyzed. The...
The creep equations of the creep damage model of the coal–rock combinations are derived according to the principle of series–parallel connection of elements and the superposition principle. (1) \(\sigma_{0} < \sigma_{s1}\) corresponds to the initial creep stage. The model is equivalent ...
(3) While these equations can be analytically solved in general by considering appropriate boundary conditions to obtain the time evolution of MT length, the steady-state behavior is of the main interest. Therefore, by setting the left hand sides of the above equations to zero, after some ...
A typicalexample of physical system for which damping forces have to beinvolved into equations is a damped spring mechanicaloscillator. Here we use two models of the damping force, beingproduced by Foucault currents and by the force of the drag inair.关键词:...
In this paper, the constitutive equations of all PTFE/Cu materials are fitted by ourselves. The dynamic and static mechanical properties of the material samples are tested at room temperature. The constitutive equations of PTFE/Cu materials at room temperature are fitted without considering the ...
