(6.191)x˙=−rω2cosωt−r2ω2lcos2ωt assuming that the velocity does not change with time in the analysis. The rotational acceleration of the big-end mass (equation [6.186]) as well as the linear acceleration of the small-end mass plus the mass of the piston (equation [6.191])...
where v is the relative moving velocity and ω the radial frequency of the motion. Note that both β1 and β2 are dependent on the specific mass of the fluid. For even higher speeds, the flow may become turbulent. In a turbulent flow the drag force is proportional to the momentum change...

The equivalent mass of the moving element at the tip, 6 mm from the pivot, is about 0.9 mg. The principal advantages of the transducer over other types is that it is nearly impervious to moisture. 展开 DOI: 10.1111/j.1748-1716.1982.tb07038.x 被引量: 40 ...
where we have assumed no-slip boundary conditions at the particle surface,u=U+ω×rbeingUthe translational velocity of the particle,ωthe angular velocity andrthe vector pointing from the center of mass of the particle to the surface of the particle. In equation (1), we have chosen a trans...
aWhere M is the mass matrix, δ (t)′′ is the 2nd time derivative of the displacementδ (t) (i.e., the acceleration), δ (t)′ is the velocity, C is a damping matrix, K is the stiffness matrix, and P(t) is the force vector. 那里M是许多矩阵, δ (t) ′ ′是displacement...

When a droplet is placed on a soft surface, surface tension deforms the substrate, creating a capillary ridge. We study how the motion of the ridge dissipates energy in microscopic droplets. Using a micropipette based method, we are able to simultaneousl
We revisit the problem of introducing an external global field -- the mass media -- in Axelrod's model of social dynamics, where in addition to their neare... LR Peres,JF Fontanari - Epl 被引量: 26发表: 2011年 A new collision avoidance model for pedestrian dynamics The pedestrians can...
When the source mass has cooled to near room temperature, we reheat it to start another run. Because the cylinder has a 5 mm slit on the side, we can change its position between a location close to the interferometer and a remote one23 without interrupting the cavity mode. This allows...
