The Restrictive Condition in Applying the Principle of Moment of Momentum to the Instantaneous Center of a Body in Plane Motion

Chen Changju  
It is proved in this paper that the principle of moment of momentum for a rigid body with respect to its instantaneous center P has a simple formula J_pε=Σm_P(F), if a constant distance is kept between the instantaneous center of rotation and the centroid of this body in plane motion. This method is rather convenient for practical application. In addition, the rationality of the proofs on this topic made by [1] and by the teaching research group, of mechanics of Zhongshen University [5] is discussed.
