We then discuss the kinetic energy of a rigid body and establish the Koenig decomposition. This decomposition, combined with the balance laws, can be used to prove a work-energy theorem for a rigid body. As illustrations of the theory, we consider four classes of problems: purely translational...
of the relation existing between the forces acting on a body, the mass distribution of the body, and the motion of the body. It is used to predict the motion caused by given forces or to determine the forces required to produce a given motion. Rigid Body Dynamics K. Craig 5 Basic ...
分别是,Mechanics, Statics, Dynamics, Kinetics. 其中Kinematics 不研究力(force),研究的是:kinematicsis the study of position,displacement, rotation, speed, velocity, acceleration, and jerk. 在中文中都是一个字,力。这个物理力学语境中"力"和我们理解的 Force 不一样。 每一个“力”都有一个明确的定义。
Knowledge‐in‐action: an example with rigid body motion The problem concerns kinetics of a rigid body, and the analysis was done in the light of Johnson‐Laird’s mental models theory and Vergnaud’s ... SSCD Costa,MA Moreira - 《Research in Science & Technological Education》 被引量: 4...
Normal human gait is one of the most complex functions of the human body. Kinematics is the study of the motion of points, bodies, and systems of bodies without consideration of the causes of motion. Motion or movement can mean physical translation of either a person or a segment of a per...
Hip joint reaction forces were calculated using inverse dynamics based on a four segment rigid body model. Vertical ground reaction force and displacement data were fit to two single degree of freedom models, the Voigt and standard linear solid (SLS). The goodness of fit was quantified using ...
Rheology is a fluid mechanics discipline that studies the deformation and flow behavior of liquid or solids materials via the measurement of parameters such as viscosity or yield stress. From: Bioresource Technology, 2022 About this pageSet alert ...
A new iterative model has been developed that couples, in the boundary layer of a reentering body, the equations for N 2, N, O 2, O, and NO mass fractions, N 2 and O 2 vibrational distributions, and gas temperature with the surface state-to-state heterogeneous recombination coefficients ...
SthK, a cyclic nucleotide-modulated ion channel from Spirochaeta thermophila, activates slowly upon cAMP increase. This is reminiscent of the slow, cAMP-induced activation reported for the hyperpolarization-activated and cyclic nucleotide-gated channel H
Attractive molecular forces give rise to singular tensile stresses and to a discontinuity of displacement at the edge of contacts. These boundary conditions are those of fracture mechanics and correspond to adding a rigid body displaceme... D Maugis,M Barquins - 《Journal of Physics D Applied ...
