Abstract
An additive decomposition of generalized constraint forces into a component determined by the motion of the system and a constitutively prescribed com ponent is discussed in this paper. The former component is shown to be nece ssary and sufficient to ensure that the motion of the system satisfies the constraint, while the prescription of the latter is shown to be at the disc retion of the dynamicist. The decomposition is also related to previous wor ks on constraint forces in the dynamics of discrete mechanical systems.
