As a matter of fact, two ball joints on each rod introduce an internal DOF for the rod which can rotate about its own axis. An arrangement such as the one depicted in Fig.3 suppresses these internal DOF and keeps the same global behaviour. To go a little further, it is possible to ...
As depicted inFigure 5, Santa Cruz Fortress comprises five defense components: bastions, an enclosure, a ditch, gates, and additional forts. The defensive system took its final form in 1734, following renovations and reinforcements by engineer Juan Ballaster, which included adding fortifications to...

Comments on the article 'Walking a Charged Pith Ball Perpendicular to an Electric Field,' by Paul J. Dolan Jr. Distance travelled by pith balls; Normality of the initial direction of the ball to the plate; Acquisition of a velocity by the ball perpendicular to the electric field....
The linear or rotary ball bearing has running wires (3) which form raceways for the ball (5). The perpendicular (6) to the center line of the raceway surface in the direction of motion of the ball is at an angle to the perpendicular (7) which passes through the center of the ball....
The coordinate origin is taken as the center of mass of the workbench and the mover, with the flexible connection between the workbench and the guide simplified as a spring-loaded damping system in the Y and Z directions and a separate damping system in the X direction. The overall mass of...

speed spindle bearings. The advantages of angular contact ceramic ball bearings are their simple structure, high rigidity, and high load-carrying capacity. But the ball bearings have the defects of large vibration amplitude and poor accuracy retention, resulting in a shorter life of the ball ...
