2. In order to define this irrotationality condition mathematically, let us consider the equation of motion in terms of velocities . 为了从数学上确定此无旋性条件,我们考虑以速度为未知函数的运动方程。 www.showxiu.com3. On the basis of establishment plane coordinate system, the equation of motion...
The motion of an aerosol can be described by a general force balance equation, independent of the detailed structure of the flow, provided that the interaction between the external flow field and the local flow induced by the aerosol is weak. A necessary and sufficient condition for the ...

Define Equation of motion. Equation of motion synonyms, Equation of motion pronunciation, Equation of motion translation, English dictionary definition of Equation of motion. n. 1. The act or process of equating or of being equated. 2. The state of being
aThe equation of motion for the inverted-pendulum model depicted in Fig 1 during the single support phase is easily derived by applying d’Alembert’s principle and taking moments about the support point or using the Lagrangian formalism 运动方程为倒置摆锤模型描述在1在支持阶段期间通过申请d’ Alemb...
Equation (2) describe waves, which are induced by gravity: no elastic resistance is present in the waveguide. Compared to (1), the differential equations governing the motion of a gyroscopic, vertically hanging rope, include variable coefficients, which depend on the spatial variable along the rop...
Question: The equation of motion of the system shown in the figure is already obtained using x as the generalized coordinate, and provided as: (m+r2l)x¨+cx˙+5kx=F0sin(ωt) The numerical values of the parameters are provided as follows: ...
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. Accelerationa = (v-u) /t Or at = (v-u) Ort = (v-u) /a Next step is to substitute the equation for the time t into the second equation of motion s=ut +...
The competitor’s speed is related to the propulsive power output and to the resistive power (depending on discipline and equipment) via the equation of motion. The control variable of a given athlete involved in a given discipline/distance is the propulsive power delivered over time, more ...
FromEq. (1)it can be deduced that the shear force is continuous everywhere except under the moving load where the force is discontinuous. This discontinuity is accounted for in the equation of motion (Eq. (1)), for all time moments, due to the presence of the generalized derivatives. Cons...
