Abstract: Freudenstein introduced the concept of generalized Burmester points using proofs involving polar coordinates. In the present paper rectangular coordinates are used; this leads to an extension and ...

Abstract: In plane kinematics there is in general in a given position of the moving plane one point J in this plane (the acceleration pole) which has the acceleration zero. Moreover, if A ≠ J is a ...

Abstract: If a plane oscillating cylinder mechanism is in the position where the slider and the crank are aligned, it has a Ball point on the slider. This Ball point coincides with the inflexion-pole. ...

Abstract: In a recent paper F. Freudenstein and E. Söylemez investigate the motion of the centers of spheres in rolling contact with two planes having coplanar motions. It appears that the said motion ...
