The last newsletter noted that Jim participated in a recent Network World chat on the topic of application performance management and WAN acceleration. Today, we’ll continue that thread by discussing ...

Note that since the top contact point of the disk rolls without slipping on the upper fixed surface, this contact point has zero velocity. In addition, the horizontal component of acceleration of that ...

Note that as link BD passes through the horizontal orientation, the velocity of B (as well as the angular velocity of AB) instantaneously goes to zero, yet the acceleration of B is not zero. In a ...
