An explicit expression for the moment in multibody systems

J Biomech. 1992 Oct;25(10):1209-11. doi: 10.1016/0021-9290(92)90076-d.


The equations of motion are formulated for a set of interacting rigid bodies. An explicit formulation could be derived for the total moment of the forces on such a system. This is applied to (1) the intersegmental moment in a multisegment rigid-body model, and (2) the interpretation of the 'centre of pressure' as defined in the studies of human posture.
