Summary
Maxwell's Rule conveys a statement of rigidity for a given truss framework. When the number of bars or supports is reduced, the truss will inevitably lose rigidity and collapse as a mechanism. This consequence can also be captured by Maxwell's Rule in a modified statement, which leads to a discussion about its interplay with states of self-stress, illustrated using the simplest pin-jointed arch.
