ABOUT PLANE PLATES IN ROTATION MOTION

In this paper the authors approached few problems of the plane plates in rotation motion. One problem approached is the determination of the support of the resultant vector of d'Alembert's fictitious forces system, for plane plates having uniform rotation motion. Also, in this paper is studied the calculus of the centrifugal moments for plane plates. Alternative methods of calculus for the position of the central axis and the centrifugal moments, based on the coordinates of the centers of mass, are proposed in paper. The methods are originals and replace the calculus with integrals.
